Dual Cross-Over Direct Acting Relief Valve (90° Ports)
A dual cross-over relief valve — it contains two opposing relief valves in a single manifold body, protecting both A and B lines simultaneously. The 90° port layout allows the motor or cylinder ports (C1/C2) to connect at right angles to the work ports (V1/V2), which suits many motor and rotary actuator mounting configurations.
This type of valve is commonly used for hydraulic motor overload and shock protection — in drives where sudden load reversals or deceleration spikes need to be safely limited.
