Parker 529831000 4-way 3-position Valve 1/4 Inch Npt

Product Description

The PARKER 529831000 is a 4-way, 3-position mechanically operated directional control valve designed for pneumatic or hydraulic circuit control in industrial and automation applications. It uses a lever-manual return actuator with a detented return type, giving the operator positive position control without requiring continuous force to hold position. The valve carries a Cv rating of 0.830 and is rated for working pressures from 0 to 150 psi. Both inlet and outlet ports are 1/4 inch NPT. Licensed tradespeople and industrial maintenance technicians are the primary installers.

This valve is suited for use in fluid power systems where a compact, manually actuated directional valve is required. The 3-position, 5-port configuration supports cylinder extend, retract, and mid-position functions in a single valve body. Typical installation scenarios include machine tool controls, pneumatic actuator circuits, and industrial process equipment requiring manual override or primary directional control. It is appropriate for both light-duty and moderate-duty cycle applications within its rated pressure and temperature range.

Key Features

• 4-way, 3-position EC configuration with 5 ports for full directional control
• Lever-manual return actuator with detented positioning for hands-free hold
• Cv rating of 0.830 supports controlled flow in compact circuit designs
• 1/4 inch NPT inlet and outlet ports for standard threaded connections
• Working pressure range of 0 to 150 psi
• Operating temperature range of 32 to 175 degrees F for broad environmental compatibility

Compatibility

Designed as an OEM-style replacement or new-installation directional control valve for industrial pneumatic and fluid power systems requiring a 4-way, 3-position, 5-port mechanically operated valve with 1/4 inch NPT porting.

Installation Notes

Installation should be performed by a qualified fluid power technician or industrial maintenance professional familiar with pneumatic or hydraulic circuit design. Depressurize and isolate the circuit fully before removing any existing valve or making new connections. Verify port orientation and thread engagement to NPT standards before applying system pressure. Do not exceed the rated working pressure of 150 psi or the maximum working temperature of 175 degrees F.
