Piston Valve

For the best quality vertex piston valve is the most preferred destinations in the international market.
piston valves are used in different industrial applications. Proven world famous seatless and glandless sealing principle, this piston valve has proven it self many times over, with its superlative performance and class vi leakage, with all critical applications like acids, gases, vacuum, heat transfer media, steam etc highly recommended for process lines such as thermic fluid, water, steam , hot water, compressed air services and other application. Piston valve is the right solution for on-off duties not only for steam but also for lpg, ammonia, acids, alkalies & thermic fluids. Effective protection for steam traps valves, pumps and other equipments from foreign particle like dust,rust and harmful scales.
Advantages of piston valves :-
zero leak isolation piston valvesgland less and seat less valve100% leak proofno erosion of piston giving long life spansealing rings- made from various materials (including ptfe) to cover virtually every known mediumstay tight during thermal expansionno leakage of toxic/aggressive mediaeconomic & easy to service, maintenance freeuser friendly
availability :-
the valves are available in pn16, pn 40, nd/16 and nd/25 rating. The flange of piston valve can be supplied in accordance to bs, din, asa, is dimensions.
The range for the valve for socket weld & screwed end is 15 nb, 20 nb, 25 nb, 32 nb, 40 nb, 50 nb as well as screwed bspt /npt ends the range for the piston valve for flange end is 15 nb to 150 nb, in flanged ends with ansi # 150 & 300provided with electric actuator & pneumatic actuator
materials of construction :-
body, bonnet & lantern bush: cast iron, cast steel, cf8 ss304, cf8m ss316,trim: ci, cs, cf8 & cf8m. In piston valve a stainless steel piston enclosed by two valve rings makes up the sealing element. The upper valve ring provides the outer seal, while the lower valve ring seals the passage. The large sealing surface on the piston skirt provides an optimam seal.
when locked, the piston simultaneously pushes any impurities which might be present in the medium ahead of itself. Therefore, media which fibrous or contaminated constituents are reliably checked as well.
