F/G-20 through D/G-12 Series pumps use C80 Series to self-prime by quickly relieving trapped vapors or air, thereby avoiding pump airlock. Then the valves automatically close to provide immediate full system pressure. The valves mount horizontally or vertically, operate in systems with a minimum discharge pressure of 75 psi, and offer 1.5 to 10-gpm flow range with temperatures to 200°F.
