As automatically closing check valves, MAG is used in exhaust steam pipes in steam turbines as well as in pressure lines of compressors in air and gas systems. The valves can be fitted with either a hydraulic or pneumatic auxiliary drive with spring loading as additional closing support.
Positive closing behaviour via spring-loaded pneumatic operation
Adjustable hydraulic damping facility
Avoidance of tendencies of the valve disc to vibrate during operation
Adjustability of slight pressure losses via the closure weight
Additional screw retention
High availability and long service life
Our GMZ check valves protect important continuous flow machines from the dangers of back flows. An extremely low degree of internal friction and a finely responsive adjustable counterweight enable the valve to react sensitively. The GMZ is additionally equipped with a pneumatic, spring-controlled drive, enabling controlled and rapid closing behaviour. It is also fitted with a hydraulic damping system to avoid any tendencies the valve disc has to vibrate during flow changes.
