A compact hydraulic integrated system for use in circuits which require pump unloading and relief protection for unloading and dumping system flow to tank. The solenoid valve unloads the pump to the tank (either normally loaded or normally unloaded) while the relief valve maintains pressure in the system.

The valve consists of a relief cartridge and a two-way normally closed or normally open solenoid. The relief valve maintains system pressure while the solenoid unloads the pump to the tank.

Compact and lightweight HIC with cartridge style valves. Easy for piping and servicing with fewer leakage points and low-pressure drop. Conveniently located ports with multiple face options for Pump, System, Tank and Gauge connections.
