Parker CV-1000-MSMS-5 Hydraulic Check Valve 100 Gpm

Product Description

The PARKER CV-1000-MSMS-5 is a hydraulic control check valve designed to allow one-directional flow while preventing reverse flow in hydraulic circuits. Built with a steel body and nitrile seals, it handles flow rates up to 100 GPM and maximum working pressures up to 3,000 psi. The valve uses Male Seal-Lok (SAE O-ring face seal) thread connections on both the inlet and outlet, providing a reliable, leak-resistant interface common in mobile and industrial hydraulic systems. Licensed hydraulic system technicians and fluid power specialists are the primary installers of this component in high-pressure circuits.

This valve is suited for use in mobile hydraulic equipment, industrial machinery, and fluid power systems where backflow prevention is required. Its compact dimensions — 3.31 inches overall length, 1.62 inches width, and 1.62 inches height — make it appropriate for tight installation envelopes. The 1-7/16-12 Male Seal-Lok ports on both the inlet and outlet sides match standard SAE O-ring face seal fittings found in a wide range of hydraulic plumbing configurations. It is typically installed inline in pressure or return circuits requiring a directional flow control element.

Compatibility

Designed as an OEM-style replacement or direct-fit component for hydraulic systems using 1-7/16-12 Male Seal-Lok (SAE O-ring face seal) port connections with flow and pressure requirements within 100 GPM and 3,000 psi.

Installation Notes

Installation should be performed by a qualified hydraulic system technician or fluid power specialist. Before servicing, depressurize the hydraulic circuit completely and verify the system is at zero pressure using a gauge before disconnecting any fittings. Ensure all mating O-ring face seal fittings are clean and undamaged prior to assembly. Follow applicable fluid power standards and equipment manufacturer torque specifications for SAE O-ring face seal connections.
