How to choose valve according to industrial requirements

Monday, December 14th, 2009

Pragmaticus 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. (more…)

Natural shapes as a source of industrial inspiration “Butterfly” shape with high performance

Monday, November 2nd, 2009

Natural shapes are widely used in industries: Planes reminding birds flight, streamline of the ships, butterfly and diaphragm valves and many others.

Take a look at butterfly valves structure. In simple terms, “butterfly” shape consists of body, stem, actuator, seat and a circular disc with its pivot axis at right angles to the direction material is flowing. The main idea of butterfly valves is simple: each component part is available in a variety of materials and completes set in order to conform the requirements of each concrete branch. Natural wisdom is embodied in this valve. Simple structure has wide application in completely different industries, from A for mining applications to Z in pharmaceutical. Look at vital sector, such as drinking water, international eco questions such as waste water and sea water treatment, desalination plants applications. In each of them butterfly valves are used successfully. It is impossible to imagine nowadays chemical industry without sterile and high quality industrial valves application. The same is about pharmacy, food and beverage manufacturing. Mining industry requires completely different metals and technical characteristics. But even in this case “butterfly” structure can be used with high performance.
