Description

3/8" Normally Open Brass Solenoid Valve – Shako PU225AN-03

The SHAKO PU225AN-03 is a high-flow 3/8" 2/2 way normally open brass solenoid valve designed for reliable control of air, water, oils and compatible fluids under 50 cSt.

The valve is de-energised open and energised closed, making it suitable for applications where flow is required when electrical power is removed. Its pressure-assisted diaphragm design provides a large 13mm orifice and Kv flow factor of 40 L/min, with a 0.5 to 10 Bar operating pressure differential.

NBR seals are supplied as standard, with optional EPDM, FKM (Viton®) and HNBR seals providing extended media and temperature compatibility. An optional
