Single Overcentre Valve

Installation information

The inlet flow is connected to ‘V2’ port, ‘C2’ with actuator port and 1/4” BSP Port to pilot pressure supply.

Features

• Yellow Zinc Plated
• No Leakage
• Internal Components Hardened
• Spring Setting Range 60 to 350 Bar
• Suitable for open or closed centre
directional control valves

 Operation

The flow passes free from ‘V2’ to ‘C2’. When descend control pressure is applied on pilot port it opens gradually and flow passes from ‘C2’ to ‘V2’ and does not allow the increased flow to increase the actuator speed.
Note : The valve should be set 30% above max load induced pressure. Max working pressure 270 Bar. Pilot ratio 1:4.25
