Series ASX

Series ASX

2/2-way - Normally Closed (NC) and Normally Open (NO)
2/2-way - Double Acting (DA)
Angle seat valves are available in different versions with regard to nominal diameter, type of fluid and process connections.
They are able to manage media that are corrosive or contain suspended solid particulate matter and can be used in applications with high operating temperatures.

The operation is determined by the pneumatic drive of a single acting, guided piston actuator with spring return.
There are also models available with double acting actuators, without spring.
For liquid media we recommend the models with flow direction under the seat.
For gas or steam we recommend the models with flow direction above the seat.
