Parker 3C20F-F65 Hydraulic Check Valve 90 Gpm 3000 Psi

Product Description

The PARKER 3C20F-F65 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 up to 90 GPM and a maximum working pressure of 3,000 psi. The 1-1/4-11-1/2 female NPTF inlet provides a pressure-tight threaded connection suited for demanding hydraulic applications. At 5.76 inches in overall length with a 2-inch width and 2-inch height, the valve fits into compact manifold and inline configurations. This valve is installed by hydraulic system technicians and industrial maintenance professionals working on mobile or stationary hydraulic power units.

The PARKER 3C20F-F65 is used in industrial and mobile hydraulic systems where directional flow control and backflow prevention are required. Typical installations include hydraulic power units, cylinder circuits, and manifold assemblies operating at high pressure. Its steel construction and fluorocarbon seals make it suitable for systems running petroleum-based and select synthetic hydraulic fluids. The female NPTF thread standard ensures leak-free connections in high-pressure plumbing without the need for additional sealants when properly torqued to fitting specifications.

Key Features

• Maximum flow rate of 90 GPM supports high-volume hydraulic circuits
• Rated to 3,000 psi maximum working pressure for heavy-duty service
• Steel body construction provides durability in industrial environments
• Fluorocarbon seals offer broad chemical compatibility with common hydraulic fluids
• 1-1/4-11-1/2 female NPTF inlet delivers pressure-tight threaded connections
• Compact envelope — 5.76 inches long, 2 inches wide, 2 inches tall — suits tight installations

Compatibility

Designed as an OEM-style replacement or service valve for inline hydraulic check valve applications requiring a 1-1/4-11-1/2 female NPTF inlet in systems rated to 3,000 psi.

Installation Notes

Installation should be performed by a qualified hydraulic technician. Depressurize and de-energize the hydraulic system completely before removing any fittings or valves. Verify that the system fluid and operating pressure are within the valve's rated specifications before placing it in service. Follow applicable ANSI and OSHA hydraulic safety standards for fitting installation and system startup.
