Brass pressure-sensitive regulating unloader for single pump and single gun installations. It maintains full system pressure while the pump runs in by-pass with minimal load. The compact size allows easy installation; the colour-coded spring identifies the pressure range and can be transferred quickly to another model. 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.
