Parker 524211000 3-way 2-position Valve 1/4 Inch Npt

Product Description

The PARKER 524211000 is a 3-way, 2-position mechanically operated directional control valve designed for pneumatic and fluid circuit applications in industrial and commercial systems. It uses a roller-spring return actuator, which mechanically shifts the valve when a cam or lever depresses the roller and returns it to the default position via spring force when the mechanical input is removed. The valve has a Cv rating of 0.83 and handles working pressures from 0 to 150 psi. Inlet and outlet ports are both 1/4 inch NPT. Licensed pneumatic technicians, fluid power mechanics, and industrial maintenance professionals are the primary installers.

This valve is suited for use in pneumatic directional control circuits where mechanical actuation is preferred over electrical or manual means. Typical applications include machine tool sequencing, conveyor control logic, and actuator cycling where a physical cam, trip dog, or mechanical trigger drives the valve. The 3-way, 2-position configuration allows the valve to pressurize or exhaust a single actuator port depending on valve state, making it a standard choice for single-acting cylinder control in automated equipment.

Key Features

• 3-way, 2-position valve design for single-acting actuator control
• Roller-spring return actuator provides reliable mechanical trip and automatic reset
• 1/4 inch NPT inlet and outlet ports for standard pneumatic line connections
• Cv rating of 0.83 supports typical small-bore actuator flow requirements
• Operating pressure range of 0 to 150 psi covers most industrial pneumatic system pressures
• Working temperature range of 32 to 175 degrees F for standard indoor industrial environments

Compatibility

Designed as an OEM-style replacement or new-installation directional control valve for industrial pneumatic systems requiring a mechanically actuated 3-way, 2-position valve with 1/4 inch NPT porting.

Installation Notes

Installation should be performed by a qualified fluid power mechanic or industrial maintenance technician familiar with pneumatic directional control circuits. Depressurize and lock out the pneumatic supply line before removing or installing the valve. Verify port thread type and size before installation to prevent cross-threading the NPT connections. Consult applicable OSHA lockout/tagout procedures and equipment OEM documentation before servicing any pneumatic circuit.
