1/2" BSP WRAS approved Brass solenoid valve 2-way normally closed model PU220D-04 max working pressure 10 Bar, differential pressure 0 to 7 Bar (AC voltage) or 0 to 6 Bar (DC voltage) with 15 Watt coil. Both solenoid coils are Nass Magnet Class H IP65 CE DIN43650A 100% duty rated and supplied with IP65 electrical connector as standard. Available voltages include 12vdc, 24vdc, 48vdc, 110vdc, 220vdc or 12vac, 24vac, 48vac, 110vac, 220vac, 230vac, 240vac or 380vac 50/60hz.
This Shako PU220D-04 Brass Assisted Lift or Zero Rated solenoid valve has a 13mm orifice giving a Kv flow factor of 35L/Min based on water with a 1 bar pressure difference, i.e. inlet pressure is 1 bar higher than outlet pressure, more flow can be achieved with higher pressure difference.
Available options include NPT thread, 18.5 Watt high power coil for higher pressures and ATEX EExmIIT4 coil for zone 21 and 22 hazardous area applications.
WRAS Certificate Number 1704353, tested and approved until April 2022. Test procedure 200,000 open and close cycles at 7 Bar +90ºC hot and 25ºC cold water, then a final 10.5 Bar pressure leak and function test.
