Brass Solenoid Valve Body 1/4 in
The Dayton 3A433 is a brass solenoid valve body designed for fluid control in plumbing and industrial systems. It suits installers and maintenance teams who need a normally closed 2-way valve for air, inert gas or water lines. The unit arrives without a coil, so the buyer must supply a compatible actuator.
Pressure and Temperature Limits
The valve handles a maximum operating pressure differential of 200 psi for both air or inert gas and water service. A minimum differential of 2 psi is required for reliable operation. Fluid temperature must not exceed 180 degrees Fahrenheit and the body carries an indoor and outdoor environmental rating.
Installation Notes and Common Issues
The 1/4 inch nominal pipe size and 1/4 inch orifice accept standard NPT fittings and yield a Cv of 1.2. Installers must verify coil voltage and power rating match the application before wiring. California Proposition 65 warnings apply because the brass contains chemicals known to cause cancer and reproductive harm.

Questions about this item
Should I pick the 1/4 in pipe size or a different port for my line?
This valve body has a 1/4 in nominal pipe size and a matching 1/4 in orifice, so choose it when your piping and flow requirements align with that diameter.
What does the Cv 1.2 rating tell me about flow once installed?
A Cv of 1.2 means the valve will pass 1.2 US gallons of water per minute with a 1 psi pressure drop, giving a practical baseline for sizing pumps and piping.
How does the 200 psi pressure rating limit actual use?
The valve handles up to 200 psi differential for both air or inert gas and water, so system pressure must stay at or below that level for safe operation.
