VALVE

  High performance butterfly valves ： Generally refers to  double eccentric butterfly valve  and  triple eccentric butterfly valve ,due to their excellent working performance and high sealing ability (compared with concentric butterfly valve) are widely used in petrochemical,power plants,metallurgy,civil heating fields.Eccentric butterfly valves have the good working performacne to meeting sever and strict requirements in many different industries.Today, we are going to introduce the application of eccentric butterfly valve in air separation for making oxygen,hydrogen,CO etc. At present,the mature air separation system is PSA(Pressure Swing Adsorption),it need certain number of programmed valves (valve parts usually double or triple eccentric butterfly valve) in its pipeline system to control and adjust the medium. FEIDA  double (and tripple) eccentric butterfly valve are widely used in this kind of PSA system due to the valves' excellent features: 1-Long s...

  The  high-performance butterfly valve  is a new type of butterfly valve designed on the basis of absorbing the advantages of several different structure butterfly valves. The sealing surface of the valve plate of this butterfly valve is a spherical arc surface body. The sealing mechanism achieves a real dynamic seal through the system pressure, so it has excellent cutting performance and durability. Its small size, light weight, wide manufacturing range and easy maintenance. The high-performance butterfly valve is mainly suitable for the drainage of water plants, power plants, steel smelting, chemical engineering, water source engineering, environmental facility construction, etc., especially suitable for water pipelines, as regulating and intercepting equipment. A  double offset butterfly valve  is an HPBFV rated for ANSI (285 @ 100F or 100 psig @ 400F for 150# ANSI) rated applications. For this type of valve, the disc and stem are double offset, (set back be...
