Model 920 - Swing Check Valve Brochure

Easy structures and short dimensions are the remarkable features of MVA swing check valves. They are to be directly mounted be-tween DIN flanges (PN 6, PN 10). The swing check valves are automatically held in a central position by the flange connection screws (pos. 6). An O-ring (pos.5) seals the equipment and protects it from external effects. Therefore, we recommend to use union liners with clean seal-ing surfaces. MVA swing check valves require a low opening pressure. The resulting opening power directs the valve against the spring (op-tional, pos. 3) and the valves weight power (pos. 2), so that the media is released.
