German Hafner valves Hafner models Hafner prices
Hafner valves are used in the field of industrial automation process control. They are the final control elements that change process parameters such as medium flow, pressure, temperature, and liquid level by accepting control signals output from the regulation control unit and using power operation. They generally consist of an actuator and a valve body. According to stroke characteristics, control valves can be divided into linear stroke and angular stroke; according to the power source used by the associated actuator, they can be divided into pneumatic control valves, electric control valves, and hydraulic control valves; according to their function and characteristics, they are divided into linear characteristics, equal percentage characteristics, and parabolic characteristics.

German Hafner coupling, Hafner model, Hafner price
The Hafner coupling connects several sets of diaphragms (thin stainless steel plates) to the two coupling halves with bolts in an alternating arrangement. Each set of diaphragms consists of multiple stacked layers. The diaphragms are available in link-type and various shapes of single-piece type. The diaphragm coupling compensates for the relative displacement of the two connected shafts through the elastic deformation of the diaphragms. It is a high-performance flexible metallic element coupling that requires no lubrication, has a compact structure, high strength, long service life, no rotational backlash, and is unaffected by temperature or oil contamination. It features acid, alkali, and corrosion resistance, making it suitable for shafts operating in high-temperature, high-speed, and corrosive media environments.
