Parker 3C20EM-EM65 Hydraulic Check Valve 90 Gpm 3000 Psi

Product Description

The PARKER 3C20EM-EM65 is a hydraulic control check valve designed to allow flow in one direction while preventing backflow in hydraulic circuits. Built with a steel body and fluorocarbon seals, it handles a maximum working pressure of 3,000 psi and a maximum flow rate of 90 GPM. The 1-5/8-12 male 37-degree flare inlet thread provides a secure, leak-resistant connection suited to high-pressure hydraulic line work. This valve is installed by hydraulic system technicians and maintenance mechanics working on industrial, mobile, or heavy-equipment hydraulic circuits where backflow prevention and pressure integrity are critical.

This check valve is appropriate for use in medium- to high-pressure hydraulic systems where controlled unidirectional flow is required. Typical applications include mobile equipment such as excavators, loaders, and agricultural machinery, as well as stationary industrial hydraulic power units. Its compact envelope and steel construction make it well-suited to environments with vibration, contamination exposure, and elevated operating pressures up to 3,000 psi.

Key Features

• Maximum working pressure of 3,000 psi for demanding hydraulic circuit applications
• Maximum flow rate of 90 GPM supports high-volume hydraulic systems
• 1-5/8-12 male 37-degree flare inlet thread for secure, high-pressure line connection
• Steel body construction for durability in industrial and mobile equipment environments
• Fluorocarbon seals provide resistance to hydraulic fluid degradation and elevated temperatures
• Compact dimensions at 6.57 inches length, 2 inches width, and 2 inches height

Compatibility

Designed as an OEM-style replacement or direct-fit check valve for hydraulic systems requiring a 1-5/8-12 male 37-degree flare inlet connection rated to 3,000 psi and 90 GPM.

Installation Notes

Installation should be performed by a qualified hydraulic technician. Depressurize and lock out the hydraulic system fully before removing or installing any hydraulic components. Verify thread type and torque connections to the fitting manufacturer specifications using calibrated hydraulic line wrenches. Inspect sealing surfaces and confirm fluorocarbon seal condition before placing the valve into service.
