Parker N1600B Hydraulic Control Valve 1 in Npt 40 Gpm 500 Psi

Product Description

The PARKER N1600B is a hydraulic control valve designed to regulate flow in hydraulic systems. Built with a brass body and a nitrile seal, it handles up to 40 GPM and a maximum working pressure of 500 psi. The 1 inch NPT inlet threads into standard hydraulic lines, and the knob handle provides direct manual flow adjustment on the line. At 4.25 inches overall length, it fits into compact plumbing arrangements. Licensed hydraulic system technicians and industrial maintenance professionals are the primary installers of this valve in mobile and stationary hydraulic circuits.

The N1600B is suited for use in hydraulic control circuits requiring manual flow regulation. Its brass construction makes it appropriate for applications where corrosion resistance is a priority and working pressures remain at or below 500 psi. The knob handle is well suited for panel-mount or inline installations where frequent manual adjustment is needed. This valve is typically found in industrial machinery, mobile equipment hydraulics, and fluid power systems where a reliable, compact inline control valve is required.

Key Features

• Brass body construction for corrosion resistance in hydraulic fluid environments
• Maximum flow rate of 40 GPM for high-volume hydraulic circuits
• 500 psi maximum working pressure rating
• 1 inch NPT inlet for compatibility with standard hydraulic line fittings
• Nitrile seal material for resistance to petroleum-based hydraulic fluids
• Knob handle design allows manual flow control without additional tooling

Compatibility

Designed as an OEM-style replacement or direct-install hydraulic control valve for fluid power systems requiring a 1 inch NPT, brass-body manual flow control valve rated to 500 psi.

Installation Notes

Installation should be performed by a qualified hydraulic systems technician or industrial maintenance professional. Depressurize and fully isolate the hydraulic circuit before removing any existing valve or fitting. Verify that system pressure and flow rate do not exceed the valve ratings of 500 psi and 40 GPM. Use appropriate thread sealant rated for hydraulic service on NPT connections and confirm all fittings are leak-free before returning the system to operation.
