Pneumatic Y-pattern Drain Valve,Drain Valve,Y-pattern Drain Valve
Pneumatic drain valves are installed in steam pipes of thermal power unit
According to their site can be divided into:
1.Main steam line drain valves
2.Hot reheat line drain valves
3.Cold reheat line drain valves
4.First stage,second stage,third stage,forth stage,fifth stage and sixth stage extraction steam line drain valves
1.Y-Type forged valve body,low flow resistance,greater Cv value.
2.Disc with throttle piece,effectively protect sealing surface,extend valve service life.
3.Disc & Seat sealing surface through special craft processing and machining,anti-cavitation,erosion-resistant
4.Processing two guide rings in disc,stem suffer force balanced,flexible movement.
5.Stem packing all of imported U.S.Garlock high-quality flexible graphite packing,good chemical properties and flexibility,low friction,long service life.
6.Fast switching-speed,normally 3-5 seconds,effective protection of system security,greatly reducing the time of the sealing surface erosion by media.
7.There are disperse heat disks in the bonnet,can fully heat dissipation which protects pneumatic actuator & accessories are not subjected to high temperature and failure.Chamber gasket is clip S.S. Wire high mesh flexible graphite with a better sealing and reliability than general type.
