Roetelmann GmbH”s fully welded ball valve offers absolute safety for toxic or aggressive media, e.g. phosgene. Even with an inner leakage, no medium can escape. The torque is transmitted contact-free by the magnetic coupling. The position of the ball can be detected from outside with absolute safety. The pressure drop in the flow path is negligible compared to bellow-seal valves. A variety of construction and seal materials are available to meet customer requirements. Welded or flanged end connections, locking devices to meet OSHA requirements, and actuators are also available.
