GHAZ®II
(10 Nm – 1.000.000 Nm)
Since 1975 Fahlke has offered a comprehensive selection of actuators for your automation projects.
GHAZ®II – GAS OVER OIL ACTUATORS
The extremely compact and powerful GEHAZ®II from Fahlke is part of the world’s most modern actuator series for automation of rotary valves. Our electro-hydraulic automation technology can be mounted on every valve, has a variable torque and is explosion-proof in accordance with Ex II 2G Ex db eb IIC T6 Gb.
The GEHAZ®II uses only 1/10 the power of an electric actuator with the same torque output.
It is ideal for smaller valves (e.g. gate and ball valves), since the compact size enables fast and easy mounting on such valves.
