Parker N600B Hydraulic Control Valve 8 Gpm 2000 Psi 3/8 Npt

Product Description

The PARKER N600B is a brass hydraulic control valve designed to regulate flow in hydraulic circuits operating at up to 2,000 psi. The valve accepts 3/8-18 NPT connections and handles a maximum flow rate of 8 GPM. At 2.5 inches in overall length and 1 inch in overall width, it fits into compact hydraulic assemblies where space is limited. A knob handle allows direct manual adjustment of flow without additional tools. Nitrile seals provide compatibility with common petroleum-based hydraulic fluids. This valve is installed by hydraulic system technicians and fluid power mechanics in both mobile and stationary hydraulic applications.

The N600B suits residential and light commercial hydraulic systems where manual flow control is required. Typical installations include log splitters, small hydraulic power units, shop presses, and similar equipment operating within the 2,000 psi working pressure range. The 3/8-18 NPT thread standard is widely used across North American hydraulic plumbing, making this valve a straightforward fit in most standard manifold or inline configurations. The brass body resists corrosion in environments where moisture exposure is a factor.

Key Features

• Maximum working pressure of 2,000 psi for common hydraulic system demands
• 8 GPM maximum flow rate suits small to mid-range hydraulic circuits
• 3/8-18 NPT thread standard for broad compatibility with North American hydraulic fittings
• Brass body construction for corrosion resistance
• Nitrile seals compatible with petroleum-based hydraulic fluids
• Knob handle for direct manual flow adjustment without tools

Compatibility

Designed as an OEM-style replacement or direct installation valve for hydraulic systems using 3/8-18 NPT connections and operating at or below 2,000 psi with flow rates up to 8 GPM.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid power mechanic. Depressurize the hydraulic system completely and relieve all stored pressure before removing or installing any valve. Use appropriate thread sealant rated for hydraulic service on NPT connections and avoid overtightening brass fittings. Verify system operating pressure does not exceed the 2,000 psi maximum rating of this valve before returning the circuit to service.
