Shako WRAS Approved 2/2 Normally Closed Solenoid Valves

Shako PU220D and PU225D WRAS approved brass solenoid valves for automatic control of potable water in plumbing, water treatment and equipment installations. These 2/2-way normally closed valves open when energised and close when power is removed. Choose PU220D assisted-lift models for operation from zero pressure differential, or PU225D pressure-assisted models requiring a minimum 0.5 bar differential. Connection sizes span 3/8" to 2" BSP across the range, with AC and DC coil options. Check each model’s working pressure, flow capacity and approved temperature range, or contact our technical team for selection advice.
