Parker RAH101S50 Hydraulic Relief Valve 30 Gpm 5500 Psi

Product Description

The PARKER RAH101S50 is a two-way hydraulic relief valve designed to regulate and limit pressure in hydraulic circuits. It provides overpressure protection by diverting flow when system pressure reaches the set threshold. Built from steel construction, this valve handles a maximum working pressure of 5,500 psi and a maximum flow rate of 30 GPM. It uses a 7/8-14 UNF thread interface and fits into a C10-2 cavity. Licensed hydraulic technicians and industrial maintenance professionals install this valve in mobile and stationary hydraulic systems where precise pressure limiting is critical to system and equipment safety.

The RAH101S50 is suited for residential, commercial, and industrial hydraulic applications where a cartridge-style two-way relief valve is required. It installs directly into any C10-2 cavity manifold block or body, making it a practical choice for mobile equipment, industrial machinery, and hydraulic power unit assemblies. Its 30 GPM flow capacity and 5,500 psi maximum pressure rating make it appropriate for medium- to high-pressure hydraulic circuits. No specific OEM or model compatibility data was provided in the product input.

Key Features

• Maximum working pressure of 5,500 psi for high-pressure hydraulic circuit protection
• Maximum flow rate of 30 GPM supports medium- to high-flow system demands
• Two-way flow regulation for straightforward pressure relief functionality
• 7/8-14 UNF thread ensures a standardized, leak-resistant connection
• C10-2 cavity size allows drop-in installation into compatible manifold bodies
• Steel body construction provides durability in demanding hydraulic environments

Compatibility

Designed as a cartridge-style replacement relief valve for hydraulic systems using a C10-2 cavity manifold with 7/8-14 UNF thread porting.

Installation Notes

Installation should be performed by a qualified hydraulic technician. Before servicing, fully depressurize the hydraulic system and relieve any stored accumulator pressure. Use appropriate thread sealant compatible with hydraulic fluid and torque the cartridge to the manifold manufacturer's specified value. Verify system pressure settings after installation before returning the circuit to service.
