structure

The angle seat valve / straight seat valve consists of a pneumatically
actuated piston actuator and a 2-way valve housing / 3-way valve
housing. The actuator is manufactured from PA or PPS. The tried
and tested, self-adjusting stuffing box ensures high tightness. The
flow-enhancing valve housing made of stainless steel or red bronze
enables high flow values.

Depending on the version, the seat of the valve is closed with or against
the medium flow.
Spring force (CFA) or pneumatic control pressure (CFB and CFI) gen-
erates the closing force on the pendulum disk. The force is transferred
via a spindle which is connected to the actuator piston.
