1/2" WRAS Approved Water Solenoid Valve – Normally Closed


WRAS Approved Brass Water Solenoid Valve for Potable Water

The SHAKO PU225D-04 is a 1/2" WRAS approved brass solenoid valve designed for potable water and general water control applications.

This 2/2 way normally closed, pressure-assisted diaphragm valve features an anti-water-hammer design with approximately 0.5 second opening and closing time to help reduce hydraulic shock. The 13mm orifice provides a Kv flow factor of 40 L/min while maintaining compact valve dimensions.

Suitable for commercial, industrial, OEM and water treatment applications where a minimum 0.5 Bar pressure differential is available.

Typical Applications

Potable water systems
Water treatment equipment
Commercial water control
Industrial water management
Irrigation systems
