1″ WRAS Approved Water Solenoid Valve – Shako PU220D-08


The Shako PU220D-08 is a 1″ WRAS approved brass solenoid valve designed for reliable control of drinking water and potable water systems. Its assisted-lift diaphragm design provides dependable normally closed operation from 0 Bar, while the slow-closing design helps reduce water hammer and pressure shock in pipework.

With a large 25 mm orifice and Kv flow factor of 170.5 L/min, the PU220D-08 provides high water flow while maintaining the benefits of WRAS approved EPDM seals, robust brass construction and stainless steel internals. It is well suited to commercial, industrial and building-services water control applications requiring certified materials and dependable long-term operation.
