Welded Pneumatic Angle Seat Valve - Overview, Technical Parameters & Selection Guide

The welded pneumatic angle seat valve is composed of a welded angle seat valve and a pneumatic actuator. It is normally closed (NC) in single-acting type by default, and normally open (NO) type is optional. A suitable sealing seat (Polytetrafluoroethylene PTFE, Para-polybenzene PPL) should be selected according to the pipeline medium and medium temperature. The valve can be combined with a solenoid valve to form an on-off type pneumatic angle seat valve, or with a valve positioner to form an analog control regulating type pneumatic angle seat valve.
