Description

1/2" Zero Pressure Brass Solenoid Valve – CS AD12

CS Fluid Power Direct-Acting Normally Closed Solenoid Valve

The CS Fluid Power AD12 is a compact 1/2" direct-acting 2/2 way normally closed brass solenoid valve designed for vacuum, zero-pressure and general industrial fluid control applications.

Unlike conventional pilot-operated valves, the direct-acting design requires no minimum pressure differential, allowing reliable operation from 0 Bar and vacuum duties while providing working pressures up to 7 Bar depending on the selected orifice, voltage and coil.

Available with 6mm or 8mm orifices, the AD12 series combines a brass body, stainless steel internals and FKM sealing as standard, with a wide range of alternative seal materials for different fluids, gases and application requirements.
