Wanner Engineering introduces C80 Series Airbleed Priming Valves for use with F/G-20 through D/G-12 Series Hydra-Cell pumps. They automatically open to allow pumps to self-prime, then close to provide immediate full-system pressure. The easy-to-install valves are available in a variety of materials and mount horizontally or vertically. Designed for operation in systems with a minimum discharge pressure of 75 psi (five bar) and tested to handle pressure up to 2,500 psi (172 bar), the valves offer a flow range of 1.5-10 gpm (5-37 L/min) with temperatures up to 200F (93.3C).www.hydra-cell.comsales@wannereng.com
