Parker MV400S Hydraulic Control Valve 5 Gpm 5000 Psi

Product Description

The PARKER MV400S is a compact hydraulic control valve designed to regulate flow in hydraulic circuits operating at pressures up to 5,000 psi. The valve features a 1/4-inch NPT inlet with a 1/4-18 thread and supports a maximum flow rate of 5 GPM, making it suited for moderate-flow hydraulic systems. The steel body provides durability in demanding industrial and mobile hydraulic applications. Nitrile seals offer resistance to petroleum-based hydraulic fluids commonly found in these systems. At 2 inches in overall length and 2 inches in overall width, the MV400S fits into space-constrained installations where a full-size valve is not practical. Installation is handled by hydraulic system technicians and industrial maintenance personnel.

The MV400S is appropriate for use in industrial hydraulic circuits, mobile equipment hydraulic systems, and fluid power control applications where precise flow management is required. Its knob handle provides manual flow adjustment at the valve body, making it practical in panel-mount or inline configurations where operator access is needed. The compact envelope and standard NPT threading allow straightforward integration into existing hydraulic plumbing without custom adapters in most setups.

Key Features

• Maximum working pressure of 5,000 psi for high-pressure hydraulic circuit service
• Maximum flow rate of 5 GPM suitable for moderate-flow hydraulic applications
• 1/4-18 NPT thread for compatibility with standard hydraulic fittings
• Steel body construction for durability under pressure and mechanical stress
• Nitrile seals compatible with petroleum-based hydraulic fluids
• Knob handle for manual inline flow adjustment
• Compact 2 inch x 2 inch footprint for space-constrained installations

Compatibility

Designed as an OEM-style replacement or service valve for hydraulic systems requiring a 1/4-inch NPT, 5 GPM, 5,000 psi-rated control valve with a knob handle and steel body.

Installation Notes

Installation should be performed by a qualified hydraulic technician or industrial maintenance professional. Depressurize and fully de-energize the hydraulic system before removing or installing any valve. Ensure all fittings are properly torqued to the fitting manufacturer specifications and that thread sealant compatible with hydraulic fluid is applied as required. Verify the flow direction and pressure rating of the circuit before returning the system to service.
