1/4 in 3-Way Pilot Solenoid Valve

This Red Hat SC8551A001MS valve is a 3-way remote pilot solenoid designed for air and inert gas systems. It suits technicians and engineers who need reliable on-off control in 1/4 in piping with a 120V AC coil.

Sustained operation at 150 psi differential

The valve maintains its rated 0.86 Cv flow coefficient while operating continuously at up to 150 psi air or inert gas differential. NBR seals and an anodized aluminium body resist wear and corrosion during extended duty cycles without pressure spikes.

Direct pipe mounting with configurable start

The 1/4 in NPT ports allow direct in-line installation without brackets. The configurable starting position lets installers set normally open or normally closed function before pressurising. A common error is wiring the 120V AC coil to DC voltage, which prevents pilot operation.

Questions about this item

How much heat or noise does the 120V AC pilot solenoid valve produce when running continuously?

The valve operates on 120V AC with a Cv of .86 and a maximum pressure differential of 150 psi for air and inert gases; it has no fan or active cooling, so heat and noise are minimal during continuous duty.

What piping and media connections are required to install the 1/4 in NPT aluminum valve?

The valve has a 1/4 in nominal pipe size and 1/4 in orifice; it requires compatible 1/4 in NPT fittings and is rated for air or inert gases only, not fuel gas or fuel oil.

Will the NBR-sealed aluminum body work with older compressed-air systems that run at lower pressures?

Yes, the valve handles a maximum operating pressure differential of 150 psi for air and inert gases, and the NBR seals are compatible with typical legacy pneumatic lines operating within that range.
