Parker PRH101S50 Hydraulic Pressure Reducing Valve 15 Gpm

Product Description

The PARKER PRH101S50 is a hydraulic pressure reducing valve designed to limit downstream pressure in hydraulic circuits. Built with a steel body and rated to a maximum working pressure of 5500 psi, it handles demanding industrial and mobile hydraulic applications. The valve features a three-way flow regulation design and accepts a flow rate of up to 15 GPM through a 7/8-14 UNF threaded connection. Hydraulic technicians and fluid power specialists install this type of valve to protect downstream components from pressure spikes and overpressure conditions. The cartridge fits a C10-3 cavity, making integration into manifold or inline bodies straightforward.

This valve is suited for use in mobile equipment, industrial machinery, and hydraulic power units where downstream pressure must be held below a set limit regardless of upstream variation. The three-way configuration allows the valve to divert excess flow or vent pressure to tank, supporting stable circuit operation. It is appropriate for both OEM manufacturing builds and field service replacement in systems running petroleum-based or compatible hydraulic fluids. The compact cartridge design and standard cavity sizing allow installation in a wide range of manifold bodies already present in the field.

Key Features

• Maximum working pressure of 5500 psi for high-pressure hydraulic circuits
• Flow capacity up to 15 GPM for mid-range hydraulic system sizing
• 7/8-14 UNF thread for compatibility with standard hydraulic manifold and inline cavities
• Three-way flow regulation design supports pressure relief to tank
• C10-3 cavity size allows direct replacement in existing manifold blocks
• Steel body construction for durability in industrial and mobile hydraulic environments

Compatibility

Designed as an OEM-style replacement or new-installation cartridge valve for hydraulic systems using a C10-3 cavity with 7/8-14 UNF thread and requiring pressure reducing function up to 5500 psi and 15 GPM.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid power specialist. Depressurize and de-energize the hydraulic system fully before removing or installing any cartridge valve. Use the appropriate spanner or hex socket sized for the cartridge body and follow the manifold manufacturer torque specifications for the C10-3 cavity. Inspect the cavity bore and sealing surfaces for contamination or damage before installation to prevent leakage or premature valve failure.
