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. High-temperature version: a stainless steel seat and needle valve eliminate weeping; fluid temperature up to 116 °C. The outlet is a barb for a 3/4" hose. The valve is set about 10 % above system pressure.
