Parker 3C20EM-EM5 Hydraulic Check Valve 90 Gpm 3000 Psi

Product Description

The PARKER 3C20EM-EM5 is a hydraulic control check valve engineered for high-pressure fluid power systems. It accepts flow in one direction and blocks reverse flow, protecting pumps, actuators, and circuits from pressure surges and backflow. The inlet is sized at 1-5/8-12 with a male 37-degree flare thread standard, rated for a maximum working pressure of 3,000 psi and a maximum flow rate of 90 GPM. The valve body is steel construction with fluorocarbon seals, making it suitable for demanding hydraulic applications where heat and chemical resistance are required. Hydraulic technicians and fluid power specialists are the primary installers of this component.

This check valve is suited for mobile hydraulic equipment, industrial hydraulic power units, and stationary fluid power circuits requiring reliable one-directional flow control. The 1-5/8-12 male 37-degree flare inlet connection is compatible with standard JIC fittings commonly found in agricultural machinery, construction equipment, and industrial presses. It is installed inline within a hydraulic circuit where backflow prevention is critical to system integrity and component protection.

Key Features

• 90 GPM maximum flow rate supports high-volume hydraulic circuits
• 3,000 psi maximum working pressure rated for demanding fluid power systems
• 1-5/8-12 male 37-degree flare (JIC) inlet thread for secure, leak-resistant connection
• Steel body construction for durability under sustained hydraulic pressure
• Fluorocarbon seals provide resistance to heat and hydraulic fluid degradation
• Compact envelope at 6.57 inches overall length with 2-inch width and height

Compatibility

Designed as an OEM-style replacement or direct-fit component for hydraulic systems using 1-5/8-12 male 37-degree flare (JIC) inlet connections operating at up to 3,000 psi and 90 GPM.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid power specialist. Depressurize and bleed the hydraulic system completely before removing or installing any valve components. Verify that all fittings and thread standards match before tightening to avoid cross-threading or seal damage. Follow applicable fluid power safety standards and equipment manufacturer guidelines during service.
