What is the difference between ball valves from other Pragmaticus valves line?
Ball valves have special disc, it is used, in turn, for controlling the flow through it.
How does it work?
Ball valves have a port (a hole) in the middle. Further, ball valves’ work can be represented as the following process: when the port is in line with both ends of the ball valve, flow will occur. When the port is perpendicular to the ends, ball valve is closed and flow is blocked.
What are the most important characteristics of Pragmaticus ball valves?
Pressure rating (PN characteristic) from 16 to 250 (ANSI Class 150 to 1500).
Sizes from 50 (2’’) to 1000 (40’’), depending on pressure rating
Ball valves body is made of metal, plastic or metal with a ceramic center. In order to make ball valves more durable, it is often chrome plated.
What about ball valves application?
Pragmaticus ball valves are widely used in industry because they are very versatile, supporting high pressure and temperature, have steel welded design, additional secondly PTEF-seal-ring, blowout system, double block and bleed system. They are easy to repair and operate.
Natural Gas Pressure Regulating Station System is the one of the huge industries there ball valves are used.
Ball valves we supply work appropriate even after years of disuse.

Ball valves – special-applications valves
April 23rd, 2010Air valves, air valves application, and air valves manufacturer
April 23rd, 2010Air valve is one type of industrial valves with wide application. This equipment is used for the flow of a fluid (gases, liquids, fluidized solids, or slurries) regulation. Regulation is made by opening, closing, or partially obstructing various passageways.
Air valves are separated by following categories: by direction in an open valve and fluid flows or by pressure from higher pressure to lower pressure. Take a look on Pragmaticus air valves characteristics:
Pressure rating (PN) characteristics are from PN 10 to PN 40 (4 times difference). And 4 time differences in sizes Pragmaticus air valves have: from DN 50 to DN 200. It is explained by different industrial requirements.

The fundamentals about CNC programming
March 30th, 2010Almost CNC equipments are working under control of special command. CNC equipment uses a word address format (letters and numbers) mostly for CNC programming. Take a look on some of CNC commands:
Coordinate system selection – N005 G54 G90 S400 M03
Rapid to XY location – N010 G00 X1. Y1.
End of program command – N050 M30
Each command is made up of CNC words. Each CNC word has a letter address and a numerical value: N010, M03 and etc. The letter address (N, S, X, Y and many others) provides information about the type of word it is:
O – Program number (Used for program identification)
N – Sequence number (Used for line identification)
G – Preparatory function
X – X axis designation
Y – Y axis designation
Z – Z axis designation
R – Radius designation
F – Feedrate designation
S – Spindle speed designation
H – Tool length offset designation
D – Tool radius offset designation
T – Tool Designation
Numerical value, in turns, provides information about word’s value. Letters and numbers tell CNC machine what to do and how to do.
So, general idea is simple:
The first, letters + numbers = command.
The second, command controls CNC machine actions.
The third, CNC machine controller will first read, interpret and execute the very first command in the program and later will continue working in sequential order.
The first command: read, interpret, execute; the second command: read, interpret, execute, and only in this order. It is clear if there is a mistake in the program, the CNC machine won’t work correctly. Programming mistake (it can be letter or numerical mistake) can have high price.
Notify, programming functions list changes for one CNC machine type to the other one. CNC user has to know all about each machine he/she works with.
Jewelry friendly: CNC engraving machine
March 8th, 2010CNC engraving machine incises a design on flat surface such as nonferrous metals (silver, golden), mirrors, glass, and natural stone (marble, granite) and etc. New CNC technology revolutionized the market for jewelers and trophy. What would you like to see on your jewelry? Picture, signature, letters, logos, faces, or other things? Each of it can be done in a matter of seconds. Nowadays nothing is impossible with CNC engraving software, based upon coordinates’ principle as software for CNC milling machine. It is a complicated, number-centric system that is powering this industry change. But the process of engraving is quite simple with PC and software’s help. CNC engraving requires understanding the basics of computer design. Of course, this process becomes more difficult speaking about industrial needs.
Engraving services are very popular in a case of making logo on business accessories and presents: watch, coins and so on. In means, jewelers have to update their systems in order to compete, because many different companies in this sphere are offering CNC engraving as a part of their portfolio.
High universality of CNC machines allows to work successfully in various segments of the industry and to reach high quality performances, thanks to a German accuracy. CNC engraving machine tools from the numerical control (numerical programmed control) are capable to carry out of a problem of almost any level of complexity. CNC engraving machines are used for diamond engraving on cylindrical objects.
As a conclusion: CNC machines have large application in different industries. The main one is to choose machine meets all requests of your industrial process and company’s needs.
A quality of German manufacturers was repeatedly confirmed throughout all history of production of machine tools. It is the main argument in favor of a choice Pragmaticus CNC machines.
Under control
March 8th, 2010There are thousands processes in industry and each of them needs to be under control. A control system consists of set of devices and valves such as:
in order to manage, command, direct or regulate the behavior of process, other devices and systems. Control valves are an integral part of control loops networked together in industrial plants to produce final products. Valves in that case are used to control conditions (pressure level, intensity of a stream). That is why industrial valves are rates for maximum pressure level, temperature characteristics. Pragmaticus valves meet all requests of industry: some valves types rated at very high pressures and temperature are available. It is also important to know about wetted materials, are they compatible with the flow of gases or fluid (according to the industry’s needs).
Control valves work can be presented as fully or partially opening and closing. Control valves at the same time are under control too, many industrial valves because of construction (have special handle attached to the stem) are controlled manually. The other ones are controlled by actuators. When the valve is very large, manual control can be very difficult, in these cases actuators are established for the purposes of automatic control. A signals, received from controllers, open or close control valves. Controller, in turn, sends signals after compare reference significance and existing conditions. Control equipment, such as industrial valves, requires attention increased twice in comparison with the others. It is like being a “head”. Head officer status always bears more responsibility then the other industrial parts do.
Trust Pragmaticus, trust valves we made.

Test stand as a symbol of high quality level
January 19th, 2010Pragmaticus, huge valves provider based in German, delivered gate valves for the test stand of one of the leading pump manufacturers in Europe.
A gate valve which Pragmaticus supply is based on Pengineering capabilities and previous industrial experience and deep manufacturing knowledge. These reasons allow Pragmaticus gate valves being used on leading pump manufacturer’s test stand.
To understand why gate valves are necessary on test stand for pumps’ checking some words about gate valves’ and pumps’ work principle.
A gate valve (so-named for working process: the part that either stops or allows flow through the valve acts as like as a gate does) opens by lifting a round or rectangular gate out of the path of the fluid. When the valve is wide open the gate is fully drawn up into the valve bonnet (reminding metro gates) and allows a stream to flow further. But there is a little pressure drop or flow restriction during passing through the valve because gate aperture for flow through has the valve the same size as the pipe in which the valve was installed.
The gate valves are mostly used for liquid streams. And in the same time the pumps are used to move fluids (liquids, slurries, or gases). A pump displaces a volume by physical or mechanical action. That is why test stands for pump checking are equipped by gate valves. Pumps displace fluid, causing a flow. According to the methods for moving a fluid, pumps fall into five major groups: direct lift, displacement, velocity, buoyancy and gravity pumps. Gate valves, established on test stand, help to check displacing process by opening and shutting a gate.
For pump manufacturer test stand allows trying operation in different condition, regimes, with open and shut gate valve. And Pragmaticus valves meet all the requirements of pumps’ industrial tests. Read the rest of this entry »
How to choose valve according to industrial requirements
December 14th, 2009Pragmaticus offers a wide range of valves for industrial applications. The valves are easy and economical way to control and check the flows. No doubt, a valve is more than just an industrial device for turning on and shutting off the flows of fluids and gases.
There are two general groups: stop and check valves (so-called basic valves’ types). Besides, more complicated industrial valves for special, sometimes unique application are also made. All existing valves can’t be classified as easy as “stop” and “check” types as well as all industrial requirements can’t be divided into two groups only. Read the rest of this entry »
Trouble shooting guide for business of any size
December 14th, 2009Everyday company’s management faces up with different problems, from PC’s malfunctions to serious failures. What can you do when your business runs into problems? What does your troubleshooting policy consist of? It is necessary to develop and maintain complex business systems where the problems may have a set of different causes.

Interim management for industry means cost-effective problem solving.
Why internal management isn’t enough? Business troubleshooting requires professional skills, developed not one or two years, and experience with proven results. Read the rest of this entry »
Swing check valves
November 23rd, 2009Swing type is the one of the check valves (name also clack valve, non-return valve or one-way valve). Check valves’ main function is to allow fluid (liquid or gas) to flow through it in only one direction. Therefore, there are some technology features of each type.
A swing check valve has a butterfly shape, where the disc, the movable part used to block the flow, that is why it swings on a hinge or trunnion, either onto the seat to block reverse flow or off the seat to allow forward flow. The seat opening cross-section may be perpendicular to the centerline between the two ports or at an angle.
Turbulence and pressure drop within the valve are very low what makes them more demanded. The next reason why this type of valves is widespread in industrial application is that swing check valves allows full, unobstructed flow and automatically closes as pressure decreases. These valves are fully closed when the flow reaches zero and prevent back flow. Read the rest of this entry »
