Parker B642000XXA 4-way Stacking Solenoid Valve 24VDC

Product Description

The PARKER B642000XXA is a stacking solenoid valve designed for directional control of compressed air and pneumatic actuators in industrial fluid power systems. It operates as a 4-way, 2-position valve with double air pilot actuation and pilot return, making it well suited for applications that require remote or cascade pilot signal control rather than direct electrical actuation at the valve body. The valve carries a Cv rating of 2.7 and operates at 24 volts DC, with a maximum working pressure of 145 psi. Rated to NEMA 4, it is built for installation in wet or wash-down environments. Licensed industrial maintenance technicians and pneumatic system integrators are the primary installers.

This valve is used in stacking valve manifold assemblies commonly found in industrial automation, material handling, and process control systems. The 3/8 inch inlet and 3/8 inch outlet ports accommodate standard pneumatic circuit sizing for medium-flow actuator circuits. The double air pilot design allows the valve to be shifted by pilot pressure signals from either end, which is common in sequenced or interlocked pneumatic circuits. Operating temperature range spans 5 degrees F to 120 degrees F, making it suitable for most indoor industrial environments.

Key Features

• 4-way, 2-position body ported valve configuration for directional actuator control
• Double air pilot actuation with pilot return for remote signal operation
• Cv rating of 2.7 for medium-flow pneumatic circuits
• 24 volt DC operating voltage
• NEMA 4 rated enclosure classification for wet and wash-down environments
• 3/8 inch inlet and outlet port sizing for standard pneumatic manifold integration

Compatibility

Designed as an OEM-style replacement or new-installation component for stacking valve manifold systems using 3/8 inch ported, 4-way directional control valves with double air pilot actuation.

Installation Notes

Installation should be performed by a qualified industrial maintenance technician or pneumatic systems integrator familiar with directional control valve manifolds. Depressurize the pneumatic circuit and isolate all energy sources before removing or installing the valve. Verify pilot supply pressure falls within the valve manufacturer specifications before applying pilot signals. Follow applicable OSHA lockout/tagout procedures and any local compressed air system codes during service.
