Product Description

1/2" Brass Normally Closed Solenoid Valve - 150 PSI

The Dema A414P.4 is a pilot-piston operated, general purpose solenoid valve. It is designed for use with water, air, light oil, and non-corrosive fluids. Do not use for gas and other hazardous or explosive fluids. With this A414P model, the stem and plunger assembly opens the port. This releases pressure on top of the piston, which opens the main valve port. This version has a 24 volt DC coil and 1/2" NPT ports.
