Brass Solenoid Valve 3/8 in

This Dayton 4A700 valve body is a normally closed, two-way brass solenoid designed for drain and trap applications. It accepts a 3/8 inch pipe connection and operates without an integrated coil. The unit suits indoor or outdoor installations where automatic fluid control is required.

Coil-free body changes installation

Because the valve ships less coil, you must supply a compatible solenoid coil that matches your voltage and enclosure needs. The brass body provides a 2.2 Cv flow coefficient and handles air, inert gas or water up to 200 psi differential pressure. Fluid temperature must not exceed 180 degrees Fahrenheit.

Check pressure and chemical warnings

Verify that your system pressure stays above the 2 psi minimum and below the 200 psi maximum for the intended media. The product carries a California Proposition 65 warning for chemicals linked to cancer and reproductive harm. Ensure the installation environment meets the indoor/outdoor rating before ordering.

Questions about this item

Will the brass body or internal seals need replacement after extended use with water at 180 Degrees F?

The brass body and 3/8 in orifice are rated for fluid temperatures up to 180 Degrees F and pressures up to 200 psi, so seal life depends on water quality and cycle frequency at those limits.

What pressure limit is reached first when the valve runs continuously at the maximum 200 psi differential?

Both air/inert gas and water share the same 200 psi maximum operating pressure differential, so that ceiling appears first regardless of the fluid used.

How much heat does the coil generate when the valve stays energised all day at 200 psi?

The coil is sold separately, so its power draw and heat output depend on the specific coil chosen for the 3/8 in brass body.
