Parker DT-620-MSMO-5 Hydraulic Check Valve 15 Gpm

Product Description

The PARKER DT-620-MSMO-5 is a hydraulic control check valve designed to allow flow in one direction and block reverse flow in hydraulic circuits. Built from steel with metal seals, it handles working pressures up to 5,000 psi and flow rates up to 15 GPM, making it suited for demanding industrial and mobile hydraulic systems. The valve uses a Male Seal-Lok inlet by Male ORB outlet thread configuration. At 1.74 inches in overall length and just over a pound at 0.313 pounds, it is a compact inline component. Hydraulic technicians and fluid power mechanics install this valve in circuits where backflow prevention is required.

This check valve is used in hydraulic power units, mobile equipment, industrial machinery, and fluid power circuits where one-directional flow control is critical. The Male Seal-Lok by Male ORB thread interface suits systems using standard SAE O-ring face seal and O-ring boss port connections. Typical applications include loader arms, hydraulic cylinders, clamp circuits, and pressure-holding circuits in both stationary and mobile platforms. The compact body dimensions of 1.06 inches wide and 1.06 inches tall allow installation in tight manifold or plumbing configurations.

Key Features

• Maximum working pressure of 5,000 psi for high-pressure hydraulic circuit use
• Maximum flow rate of 15 GPM for sizing into compatible circuit designs
• Male Seal-Lok x Male ORB thread interface for leak-resistant SAE port connections
• Steel body construction for durability in hydraulic fluid environments
• Metal seal material for reliable seating at elevated pressures
• Compact form factor at 1.74 inches overall length for space-limited installations

Compatibility

Designed as a direct-fit hydraulic check valve for systems using Male Seal-Lok inlet and Male ORB outlet port connections rated for up to 5,000 psi working pressure and up to 15 GPM flow.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid power mechanic. Depressurize and bleed the hydraulic system completely before removing or installing any valve components. Verify that thread types, port sizes, and pressure ratings of the circuit match the valve specifications before installation. Observe applicable fluid power safety standards and equipment manufacturer guidelines during service.
