WRAS & WRc approved solenoid valves
Potable water or Drinking WRAS water solenoid valves that connect directly to UK and Euro zone mains water supply require the appropriate water approvals. The UK accepted approvals are WRAS (Water Regulations Advisory Scheme) and WRc (Water Research Centre) and within the rest of the Euro zone require DVGW and KTW approvals which may include the homogenisation's of UNI EN 681-1/2003 WB e WA, DVGW W270, DVGW W534, CLP, ACS, KIWA, TGM-LMG 75.
WRAS approved solenoid valves for mains water applications are available in most sizes from 1/2" up to 2" thread for both 2/2 way normally closed and normally open that fully conform to the water regulations with elastomer seals conforming to BS6920 (Test for water quality) and have passed the vigorous testing of 200,000 open / closed cycles at maximum pressure and temperature and a final 150% over pressure leak and temperature test. See below valves with WRAS approval:

WRc approval.
WRc Approval ® "fit for purpose" certification is a voluntary scheme conducted by the Water Research centre to help solenoid valve and other water equipment suppliers and manufacturers demonstrate quality of manufacturing and performance. More importantly products used on water applications that conform to WRc quality, installation and performance will protect our delicate drinking water system from dangerous and harmful debris, chemicals and solvents which could leach dangerously back into the water system and be consumed.
WRc approval and certification offers value to International, Euro Zone and UK companies with existing approvals from USA, Holland, Japan, France, Austria, New Zealand, Australia and Germany.
WRAS approved solenoid actuated valves either brass, stainless steel or plastic for use with UK, England, Ireland, Scotland and Wales mains water, potable water and potable drinking water systems. Zero Rated - valve operates from vacuum to maximum working pressure, Pressure assisted - valve requires minimum pressure difference between inlet and outlet port. Sizes 1/4-2" thread & speed fit 6, 8, 10 and 15mm or 1/4, 3/8 & 1/2".
