Perfect in Function and Bodywork!

Flexibility is the trump card.

Forced-pilot-operated valves combine the advantages of servo-assistant and direct-operated valves. The valves switch without pressure difference and can be used equally for small to large pipe diameters without an extreme increase in the power of the solenoid actuators.
An unusually large variety of options make this category the specialist par excellence.

Performing a lot with little energy.

Profit from the advantages of servo-controlled solenoid valves if it is ensured that there is a minimum pressure difference between input and output. The specification of the min. pressure difference can be found in the data sheets.

The expert with the extra power.

As you might expect from direct-acting valves, the solenoid power must work against the medium pressure and spring, without the assistance of the own medium or an external medium. If small nominal seat diameters can still manage relatively small solenoids, the actuator size increases exponentially with increasing pressure and seat size.

The Top Models for cryogenic technology.

Cryogenic solenoid valves for cryogenic liquids and gases down to -200°C. Win your advantage from the features: fast response, defined fail-safe position NC or NO and pure electrical. Ask also specifically for cryogenic valves for use in the food industry.

High process temperatures? A matter of preference.

The maximum medium temperature depends on the type of sealing element and the material. For this section we classify valves for temperatures between +110°C and +300°C.

Explicitly for O2, CO2, fuel gases like H2, CH4 and of course air.

We define high pressure when the operating pressure exceeds 40 bar_abs. High-pressure valves can be selected as direct-operated, forced-pilot-operated and servo-assistant valves. The valves have special housing and sealing materials. The solenoid tube system is also exposed to pressure, which requires special measures to ensure pressure stability. The limit is 1050 bar overpressure and is of exemplary interest for the green transformation in the H2 industry.

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.

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.

Basic concept seat or ball?

Seat valve with disc seal and lifting spindle, or ball valve, 90°rotation of the ball in sliding shells. With extension for cryogenic applications down to -200°C. Reliability and high switching cycles are on board as standard. Of course with spring-loaded closing (NC) or spring-loaded opening (NO)

Valve Tuning

We say yes, with the proven ingredients for electro-pneumatic poppet valves. Already many standard valves have +200°C medium temperature written into their specifications. With a little more `german engineering`, the +400°C is achievable.

Air-controlled valves combined with high pressure

Up to 160 bar our favourite, above that it is not our shining star in the sky. Our range is equally thin. We avoid the effort of sealing 4 points: To the valve outlet, medium to the outside, medium to the control chamber, control chamber to the environment. But no rule without exception!
