Stainless steel pop-off valve for CAT PUMPS high-pressure pumps. Lightweight and compact, it mounts directly into the discharge line, ideally ahead of the pressure regulator or unloader. As a secondary relief valve it provides back-up protection alongside the primary pressure control and ensures complete pressure relief; it does not replace a pressure regulator or unloader. A hardened stainless steel seat and an acetal needle valve eliminate weeping. Fluid temperature up to 82 °C; for higher temperatures there is the version with the suffix S (up to 116 °C). The outlet is a barb for a 3/4" hose. The valve is set about 10 % above system pressure.
