Brass 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. The outlet is a barb for a 1" hose. Maximum relief setting 303 bar, fluid temperature up to 82 °C.
