Mature technology for a broad range of applications
Our tight shut-off valve MAK is a universally utilisable product with triple-eccentric valve technology, suitable for extreme operating conditions and a high number of actuations. This type of valve has been successfully used since the 70s and is the further developed version of the original Adams patent.

Our MAK valves are so outstanding due to their high degree of reliability. This type of valve has proven its worth in a wide range of applications over decades. This not only means that we have been using the tight shut-off valve MAK with great success worldwide for almost 40 years, it also means that quite a number of customers are using valves we supplied decades ago, which are still in good working order in their plants. That is reliability.

One-hundred-percent tightness
We have remained true to the basic principle of the triple-eccentric design, which enables the valve to close one-hundred-per-cent tight. Despite this, we have continued enhancing details of this design over the years. For example, the MAK is equipped with a seal in the valve body. This protects the seal from the flowing medium, making maintenance intervals longer and increasing its service life. The special design of the seal enables the valve to be opened and closed without friction, even when working under great differences in temperature and full nominal pressure.

The MAK can be used for a broad range of temperatures and pressures. The MAK has proven to be highly efficient under conditions such as:

• Steam
• High temperature
• Low temperature
• High medium flow speeds
• High pressures
• Aggressive media
• Abrasive media
