As automatically closing check valves, MAG and GMZ are used in exhaust steam pipes in steam turbines as well as in pressure lines of compressors in air and gas systems.
Excellent tight shut-off behaviour
Minimal pressure losses
Additional screw retention
Minimal maintenance cost
The hallmark of the MAG is an external balancing weight that optimally counterbalances the valve disc. The advantage is that the valve is very responsive and the disc reliably reaches its final closing position. Due to the positioning of the balancing weight in its own pressure-resistant body without gland shaft seals, the valve exhibits low internal friction, which benefits the optimal closing and opening characteristics.
