Well combined
Our combined function valve GBZ/AZI provide a particularly efficient solution: they combine tight shut-off, throttle and check valves in one single unit.
The GBZ and AZI combination valves are especially space-saving as their triple function replaces the two valves that would have otherwise been necessary the check and shut-off elements.
Its shut-off and control operations are achieved via an overrunning clutch. An advantage is that the hydraulically damped disc can move freely and closes automatically and shock-free if a pump fails. Therefore this type of valve is particularly reliable and economical. The combined function valve GBZ/AZI is equipped with a hydraulic damping system separate from the operating medium, externally fitted and multi-adjustable.
