Brass pressure-sensitive regulating unloader for single or multiple gun applications. It maintains full system pressure while the pump runs in by-pass with minimal load. The pressure is adjusted externally and secured with a locking nut against over-pressurisation. The lightweight flow-through design allows compact installation. NBR O-rings are standard (fluid temperature up to 60 °C); other O-ring materials are available for higher temperatures and chemical compatibility. The valve can be converted to a secondary relief valve.
