Angle seat valve


1) PV300 Series Plunger pilot angle seat valve is propelled by piston actuator, either single acting or double acting.Actuators are made of three different materials, applicable to different working temperature.

2) 2/2 ways stainless steel valve with big flow capacity, and V type seals ensure reliable and effective sealing.

3) Maintenance free, compatible with various accessories. Direction indicating, stroke limiting or manual switching can be achieved conveniently. 

4) High flow rate. Long life cycle.

5) NC and NO universal actuators with modular universal accessary program up to control heads.

6) Deliverable with flow direction below or above seat. Simple conversion of the circuit function.

Control functionActing typeFlow direction* Water hammerApplication
Normally closedSingle actingUpsteamYesFor compressible medium(such as gas&steam) and liquid of comparatively low pressure
DownsteamNoFor anti water hammer pipeline, bears certain pressure difference
Double actingUpsteamYesReliable performance,bears pressure difference,valve closes automatically in case of an emergency
DownsteamNoFor pipeline requried of better anti water hammer,bears big pressure difference.
Normally open
UpsteamYesFor pipeline where valve keeps open, double acting & normally open when silencer comes off
DownsteamNoFor pipeline where valve keeps open,anti water hammer, double acting & normally open when silencer comes off

* Water hammer(or more generally fluid hammer) is a pressure surge or wave caused when a fluid(usually a liquid but sometimes also a gas) in motion is forced to stop or change direction suddenly(momentum change). A water hummer commonly occurs when a valve closes suddenly at an end of pipeline system, and a pressure wave propagates in the pipe. It is also called hydraulic shock. This pressure wave can cause major problems,from noise and vibration to pipe collapse. It is possible to reduce the effects of the water hummer pulses with accumulators, expansion tanks, surge tanks and other features.  Designed to close against the flow. Will not chatter or produce water hammer. Operates smoothly and quietly.
