Landefeld PDE 050-F50 Pneumatic Rotary Actuator Size 50 from , spring-closing

The pneumatic rotary actuator Size 50 from Landefeld, also known as a swivel actuator or quarter-turn actuator, with type number PDE 050-F50, is a component used in electrical systems and motor technology for precise process control. This version is designed to be spring-closing, meaning that the actuator automatically moves to the closed position if the control air fails. It has the dimensions 50 x 50 x 40 cm and weighs 35 kg. Pneumatic rotary actuators serve for the automatic control of valves, flaps, and throttles by generating a rotary movement of, for example, 90 degrees. They find typical applications in automation technology, mechanical engineering, the chemical industry, and in water and wastewater management for precise regulation of media flows.
