Pro-source 6938011035PRO Stacking Solenoid Valve 2-way

Product Description

The PRO-SOURCE 6938011035PRO is a 2-way, 2-position stacking solenoid valve with air pilot actuation and air pilot return, designed for industrial fluid control applications. It carries a Cv rating of 4.5 and operates at 110 volts AC, handling flow rates up to 105.95 cubic feet per minute. Rated for a maximum working pressure of 145 psi and a maximum working temperature of 356 degrees F, this valve is built for demanding service conditions. Licensed HVAC technicians, plumbers, and industrial mechanics install this type of valve in pneumatic and process piping systems where reliable directional flow control is required.

This valve is rated for use with compressed air, hot water, and steam, making it suitable for both HVAC process lines and light industrial steam distribution systems. The stacking design allows for modular valve assembly in manifold configurations, reducing plumbing complexity in multi-circuit systems. Inlet and outlet port size is 3/8 inch on both sides, fitting standard quarter-turn and threaded pneumatic fittings commonly found in commercial and industrial installations.

Compatibility

Rated for use with compressed air, hot water, and steam systems. Designed as an OEM-style replacement or new-install stacking solenoid valve for industrial and commercial pneumatic or process piping applications using 3/8 inch ported manifold systems at 110 volts AC.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or qualified industrial mechanic familiar with pneumatic and steam systems. Isolate and depressurize the system completely before removing or installing any valve components. Verify that the supply voltage matches the 110 volt AC coil rating before energizing. Consult applicable codes including ASME B31.3 for process piping and local authority having jurisdiction requirements for steam service.
