Use our 8.711-231.0 Pressure Relief Valve on Hotsy, Landa, Karcher and other brands of hot water pressure washers to protect the pressure washer operator and equipment from high pressure build up within the pressure washer coil system. This pressure relief valve can be used at 3000 Max PSI. The 3/8″ MPT Inlet plumbs easily to most coil outlet manifolds, and the 3/8″ Hose Barb Outlet accepts low pressure hose to allow a relief path for the hot water, typically plumbed to relief onto the floor below the pressure washer, to avoid burn injuries to the pressure washer user.
