Item description
Materials:
Body: Aluminium anodised and galvanised steel, seals: NBR
Temperature range:
-10 to +70 °C
Operating pressure:
1 to 10 bar
Media:
oiled and unlubricated, filtered compressed air, neutral and non-hazardous gases
Function:
The check valve function can be used for a brief intermediate stop of an actuator. If there is a control signal on the actuating connection, the flow between the banjo and male threads is possible in both directions. If there is no control signal, the valve locks the flow from the male thread to the banjo (venting the actuator), thus causing it to stop briefly. The flow from the banjo to the male threads (towards the actuator) is unaffected by the control signal.
