Parker F800B Hydraulic Control Valve 15 Gpm 1/2 Inch Npt

Product Description

The PARKER F800B is a hydraulic control valve designed to regulate flow in hydraulic systems operating at pressures up to 2,000 psi. Built with a brass body and fitted with a knob handle, this valve provides manual flow control in demanding fluid power applications. It accepts 1/2-14 NPT threaded connections and supports a maximum flow rate of 15 GPM. The nitrile seals offer solid resistance to petroleum-based hydraulic fluids. At 3.44 inches overall length and 1.19 inches wide, the F800B is a compact unit suited for installations where space is limited. Licensed hydraulic system technicians and industrial mechanics are the primary installers.

The F800B is suited for use in mobile hydraulic equipment, industrial machinery, and stationary hydraulic power units. Its 1/2-inch NPT inlet makes it a straightforward fit in standard hydraulic plumbing circuits. The knob handle allows for manual adjustment without additional tooling, making it practical in both original equipment builds and service replacement scenarios where a reliable, adjustable flow control point is needed.

Key Features

• Maximum working pressure of 2,000 psi for use in medium-pressure hydraulic circuits
• Maximum flow rate of 15 GPM to match common hydraulic pump outputs
• 1/2-14 NPT threaded connections for standard hydraulic plumbing compatibility
• Brass body construction for corrosion resistance in hydraulic fluid environments
• Nitrile seals compatible with petroleum-based hydraulic fluids
• Knob handle allows manual flow adjustment without additional tools

Compatibility

Designed as an OEM-style replacement or upgrade control valve for hydraulic systems using 1/2-inch NPT plumbing rated for up to 2,000 psi working pressure.

Installation Notes

Installation should be performed by a qualified hydraulic technician or industrial mechanic. Depressurize and lock out the hydraulic system completely before removing any existing valve or fitting. Apply thread sealant appropriate for hydraulic service to NPT threads and tighten to the fitting manufacturer's specification using a wrench on the valve body flats. Verify all connections for leaks before returning the system to full operating pressure.
