The valve consists of a seat by-pass, relief valve fitted with
an auxiliary control with a differential piston and by-pass
single-way valve serving for reverse direction of flow.
Description:- The valve prevents runaway in the event of a negative load
- Load-holding with minimal leakage
- Pressure relief function protecting the actuator against overload and pressure peaks
- When installed into the actuator the valve can be used as a hose burst valve
- When used as pressure relief the check valve will act as an anti-cavitation valve
- The valve should be mounted as close as possible to the actuator
- Fits the same cavity as the R3 check valve
Features:- Pressures: up to 350 bar
- Flow rate: to 90 l / min
