Application

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

Valve characters

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.
