Butterfly valves applications are wide. They are higher claimed on industrial market. “Butterfly” shape represents body, seat and a circular disc with its pivot axis at right angles to the direction material is flowing. Disc can be considered as one of the main functional detail of butterfly valve and controlled by the actuator. Materials it is made from, such as stainless steel, bronze, aluminum, iron are approach to variety of industrial demands.
Thanks to valves’ disc, butterfly valves applications consist from controlling the flow of gas, air and also dry materials may be handled through a tube or circular pipe, depending on industry’s requests. Generally butterfly valves are specified for air, gas, steam, and liquid applications.
High demand for this type of industrial valves is explained by, firstly, industrial development and huge international projects, such as gas pipelines building. Secondly, they have simple structure and wide application: gases and liquids can be easily displaced by butterfly valves’ disc as it closes. Especially so far as concerns distribution and directory changing questions. Third reason is economical price that is also important for each industry. Butterfly valves provide a reliable, bubble-tight, bi-directional shut off.
High performance butterfly valve was proved in many industries, except oil and gas: chemical; pharma; mining; food; water treatment and many others.
Chemical industry application
Each industry has own specific requirements, that’s why our goal is to correspond соответствовать to individual specification made by or for each client. High performance and high quality are the things we can proud.
The features characterize butterfly valves in chemical industry are the following: better abrasion resistance, lower permeability, lower cold flow and some others. Our valves made from metals taking into account high pressure and high temperature applications.
Pharmaceutical and food industry
Experience of our company shows that in the pharma industry sterilization is not only but one of the major features. In comparison with gas or oil pipelines where rough metals can be used in butterfly valves manufacturing, pharma requests high quality alloy and special packing. Food industry has similar requirements.
Butterfly valves for water systems
Many years high quality valves with “butterfly” shape are successfully used in vital water sector: drinking water, waste water and sea water treatment, in desalination plants, водопровод.
Depending on functional purposes butterfly valves can differ: diameter, number and structure of control module.
Personal approach to each client’s requirements is a basic of our work and a guarantee of high industrial performance. Our experience and our clients trust is our best guarantee we may give.
Wide range of butterfly valves by Pragmaticus is approach to many other industries with complete confidence.
Whether in general situations or in specific tasks we provide high quality of valves for industrial applications: air valves, energy valves, valves for checking and controlling, high pressure, gate and the other industrial valves.
