We combine the advantages of the control types direct, servo and externally controlled. The larger the valve and the higher the pressure, the more effective the use of these valves. For water control, these valves are preferably equipped with a damping cone to prevent the water hammer.

Servo-Assistant

Obsolete Valve category with reduced range of options and limited to a very small number of applications. This category has a permanent place in the "Riding a Dead Horse" section and will be removed from the programm.

Best Value for Money Use the existing compressed air system to control the stroke actuator and you have a long-life valve for a wide range of applications. The well-known 63 series, whose forerunner, the 62 series, was launched in 1971 with its characteristic formed blank cylinder, is the best indication of this high-quality product category. Even today, 25 years after the end of production of the 62 series, repair and service enquiries are still coming in from all over the world.
