Brass Solenoid Valve 1/4 in Normally Closed
The Dayton 1A575 is a brass solenoid valve body designed for drain and trap applications. It suits installers who need a two-way, normally closed valve for air, inert gas or water lines. The 1/4 inch pipe size fits standard fittings in residential and light commercial plumbing.
Critical spec: 0.34 Cv with 1/8 in orifice
Flow capacity is defined by a coefficient of volume of 0.34 and an orifice diameter of 1/8 inch. This determines whether the valve can deliver the required flow rate at your system pressure. Buyers who need higher flow capacity will find this valve insufficient.
Sold as valve body less coil
The package contains only the brass valve body; a compatible coil must be sourced separately to actuate the valve. This allows selection of the exact voltage and enclosure rating the installation demands. Installers who expect a ready-to-wire assembly must order the coil separately.

Questions about this item
How does the 0.34 Cv flow coefficient affect performance in a real system?
The 0.34 Cv rating means the valve allows a modest flow rate suitable for small-diameter lines; actual throughput depends on your inlet pressure and the fluid viscosity.
What does the 150 psi maximum pressure differential cap in practice?
The 150 psi limit applies to both air and water service; exceeding it risks seat leakage or body damage, so regulate upstream pressure accordingly.
What pipe threads and clearance does the 1/4 inch brass body need to mount?
The valve uses 1/4 inch nominal pipe threads on a two-way brass body with a 1/8 inch orifice; allow space for the coil and wiring above the body.
