STOP STP-B brass pneumatic shut-off valve with GW

STOP valve series STP-B with internal thread is a pneumatically controlled valve. It allows air flow through the valve upon simultaneous application of a pneumatic control signal (pilot). In the event of a loss of the control signal, the valve is closed in both flow directions. The STP-B valve installed in the actuator supply connection causes, in the absence of pressure at the control connection (pilot), the stopping of the actuator movement. The use of STP-B valves as safety valves should be preceded by an appropriate risk analysis of the pneumatic system or the entire device. Operating pressure: 0.5 to 10 bar. Operating temperature: from -10°C to +60°C. Body material: nickel-plated brass. Sealing: NBR.
