Parker 3C20F-F65A Hydraulic Check Valve 90 Gpm 3000 Psi

Product Description

The PARKER 3C20F-F65A is a hydraulic control check valve designed to allow flow in one direction while preventing reverse flow in hydraulic systems. Built with a steel body and nitrile seals, it handles a maximum working pressure of 3,000 psi and a maximum flow rate of 90 GPM. The 1-1/4 inch Female NPTF inlet provides a secure, pressure-tight threaded connection. At 5.76 inches in overall length, 2 inches wide, and 2 inches tall, this is a compact unit suited for inline hydraulic circuit installations. It is typically installed by hydraulic system technicians and fluid power mechanics in industrial and mobile equipment applications.

This check valve is applicable in hydraulic circuits requiring reliable one-directional flow control and backflow prevention. Common installations include industrial machinery, mobile hydraulic equipment, and power unit assemblies where maintaining circuit integrity under sustained high-pressure conditions is essential. The Female NPTF threading ensures compatibility with standard NPT hydraulic plumbing and fittings commonly found in these systems.

Key Features

• Maximum working pressure of 3,000 psi for demanding hydraulic applications
• Maximum flow rate of 90 GPM for high-volume hydraulic circuits
• 1-1/4 inch Female NPTF inlet for secure, leak-resistant threaded connection
• Steel body construction for durability under high-pressure conditions
• Nitrile seals provide reliable resistance to hydraulic fluid degradation
• Compact envelope: 5.76 inches long, 2 inches wide, 2 inches tall

Compatibility

Designed as an OEM-style replacement or direct-fit component for hydraulic systems using 1-1/4 inch Female NPTF inline check valve configurations rated up to 3,000 psi and 90 GPM.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid power mechanic. Before servicing, depressurize the hydraulic system completely and relieve all stored pressure in accumulators or actuators before disconnecting any fittings. Apply appropriate thread sealant to NPTF connections per the system manufacturer's guidelines and verify proper flow direction arrow alignment during installation. Follow all applicable OSHA and industry safety standards for hydraulic system service.
