Hydraulic Pilot Pressure Valve - HP Series
Brand: Gresen - by ParkerParker’s HP50 Pilot Generation Valve eliminates the needs for a separate pilot pump and relief valve for a pilot system. The HP50 generates pilot pressure via a sequence valve.
From there, the pilot oil is then sent to a pressure reducing valve that protects the pilot system from high pressure oil. An optional relief is also available to limit system pressure and protect the main pump.
Additionally, an optional solenoid unloading kit is available that can be energized for 300-500 PSI build up only when needed.
Features- Solenoid Kits available
- Simplifies plumbing for a pilot system
- Optional main system relief valve available
- Easily installed into an existing hydraulic system
- Eliminates separate pilot pump and relief valve for a pilot system
- The pressure reducing valve is capable of 5 GPM maximum pilot flow output
- The HP50 is rated at 3,500 PSI and the maximum recommend pump flow is 50 GPM
- Standard porting options are SAE-24 for the main Pump/Tank and SAE-6 for the Pilot output port
