Brass 3-Way Solenoid Valve Body

The Dayton 4A703 is a brass solenoid valve body with a 1/4-inch pipe size and a configurable 3-way, 2-position design. It is suited for controlling air, inert gas or water in industrial fluid-power circuits where a compact direct-acting valve is required.

Verify Port Size and Pressure Before Installing

Confirm that your system uses 1/4-inch NPT connections and that the operating pressure stays within the 0 to 125 psi range for both air and water service. The valve body is rated for fluid temperatures up to 180 °F and carries an indoor/outdoor environmental rating, so ensure the surrounding conditions match these limits.

Replaces Worn Brass Valve Bodies in Existing

This body replaces a failed or leaking brass valve body in the same manifold without changing pipework or coil specifications. The upgrade is worthwhile when the original body shows seat erosion or corrosion that degrades the Cv .05/.06 flow performance, restoring reliable shifting in the same footprint.

Questions about this item

Does the Dayton 4A703 come with a coil or do I need to order one separately?

The supplier title lists this as a brass solenoid valve body less coil, so you will need to purchase a compatible coil separately.

The spec sheet shows two Cv values, .05 and .06 — which one should I use for sizing?

Both figures are provided by the manufacturer; use .05 for the more conservative flow calculation or .06 if your system can tolerate the slightly higher capacity.

Will this valve handle 125 psi air pressure at the 180 °F temperature limit in my application?

The brass body is rated for a maximum operating pressure differential of 125 psi for air or inert gas and a maximum fluid temperature of 180 °F, so it meets those limits when a suitable coil is installed.
