During the coupling procedure, the valve chamber is sealed before the valves open. When uncoupling, the valves are already closed, before the connection can be pulled out of the seal. Can be coupled up to max. 50 bar under pressure
Materials:
zinc plated steel, seal: NBR
Temperature range:
-20 to +100 °C
Advantages:
•secure against pressure thrusts and pressure vibrations,
•streamlining design of the flow rate range
