Enerpac V66F Pilot Operated Check Valve 1.94 Gpm 10000 Psi

Product Description

The ENERPAC V66F is a pilot operated check valve designed for high-pressure hydraulic circuits requiring controlled flow in one direction with pilot-activated reverse flow capability. Built with a steel body, it handles working pressures up to 10,000 psi and a maximum flow rate of 1.94 GPM, making it well suited for demanding hydraulic power and control applications. The 3/8-18 NPTF inlet ensures a pressure-tight threaded connection without the need for additional sealing tape or compound. Hydraulic technicians and maintenance professionals install this valve in systems where load holding, cylinder control, or circuit isolation is required.

The V66F fits into industrial and mobile hydraulic systems where a pilot operated check valve provides positive load holding or prevents reverse flow under pressure. Typical installations include hydraulic cylinders, presses, lifts, and clamping circuits where backflow must be blocked until a pilot signal releases the valve. Its compact envelope and standard NPTF threaded connections make it compatible with common hydraulic manifolds and plumbed circuit assemblies used across a range of equipment types.

Key Features

• Pilot operated design allows controlled reverse flow when pilot pressure is applied
• Rated to 10,000 psi maximum working pressure for high-pressure hydraulic circuits
• 1.94 GPM maximum flow rate suits single-acting and double-acting cylinder applications
• 3/8-18 NPTF inlet provides a leak-resistant threaded connection
• Steel body construction for durability in industrial service environments
• Compact dimensions support installation in space-constrained hydraulic assemblies

Compatibility

Designed as an OEM-style replacement or direct-fit valve for high-pressure hydraulic circuits using 3/8-18 NPTF threaded connections and operating at pressures up to 10,000 psi.

Installation Notes

Installation should be performed by a qualified hydraulic technician. Depressurize and isolate the hydraulic circuit fully before removing or installing any valve. Verify that the pilot line connection and inlet orientation match the circuit schematic before tightening. Do not exceed the rated working pressure or flow rate specified for this valve.
