Description

11/2 Brass Solenoid Valve – Shako PU225A-14


The SHAKO PU225A-14 is a very high-flow, pressure-assisted 11/2" brass 2/2 way normally closed solenoid valve designed for industrial applications where a minimum pressure differential is available. Its large 38mm orifice provides an excellent Kv flow factor of 367 L/min.

Suitable for air, water, oils and compatible fluids and gases, with NBR seals as standard and optional EPDM, FKM (Viton®) or HNBR seals for extended media and temperature compatibility. Degreased and ATEX hazardous-area versions are also available.

Needed 4 of the 11/2 valves for our water system, glad to see you had stock!! Valve fitted and working very well. Ideal water control valves for us and much faster and cheaper than those actuated ball valves we used before. Thanks. Gary Hopkinsen
