Collection:Stainless Steel Solenoid Valves For Swimming Pools

Stainless steel solenoid valves for swimming pools. The valve housings and internal parts are manufactured from stainless steel. The housing is made from the austenitic stainless steel grades 304 or 316, and the internal plunger is made from the ferritic grade 430. The 400 series has a lower corrosion resistance than the 300 series. Therefore, standard stainless steel solenoid valves are not suitable for aggressive applications, such as water treatment systems. For these applications, better solutions are for example a PVC ball valve, or a medium separated solenoid valve (the internal parts are separated from the liquid). Solenoid valves can be direct operated (no pressure differential required) or indirect operated (differential pressure of at least 0.5 bar required). Solenoid valves are suitable only for clean liquids, dirt (sand, hairs) causes problems and electric ball valves provide a better solution.
