Installed 3 NC ASCO Red Hat solenoids the other day on a water line going into a chrome fume scrubber unit at a local chrome shop. The shop is in a fairly high pressure water location - id say our main after the city meter runs at about 70-80 psi. The valves were working properly until this morning when one valve wouldn't shut off. Took the valve apart - seat intact, no substantial debris. Took the power completely off just to see if this normally closed valve would hold water - water still getting through. Im wondering if you guys have experienced any malfunctioning of these valves when being used at or close to their max. rated pressure (100 psi on this model). Any thoughts? PRV? Thanks in advance.
