Change from two to one column Change from one to two columns Control Valve 23 / 24 Singleseat straightway valve with exchangeable seat ring Brief description The singleseat straightway valve 23 / 24 is a final control element for continuous control through variation of the media or energy flow in tubes. Actuation is through compressed air from a multispring diaphragm actuator. Valve housings of different nominal diameters, pressure levels, materials and internal trims (seat/cone assemblies) are available to enable optimum adaptation to the operating data. Additionally, different Kvs values are possible. A special feature of 23 / 24 control valves is the design and mounting of the seat ring. Instead of a screwtype seat ring, a laidin one is used, which can be exchanged easily. Optionally the ring is symmetric and can be used from both sides. Simply turn it by 180.Usually, a maintenancefree double seal with PTFE lip rings and a profiled fine seal is used for the valve stem. A pure graphite / Inconel packing with adjustable pressing and a hermetic bellows seal are optionally available. The multispring diaphragm actuator combines a compact design with a low height. The valve is actuated through compressed air of max. 6 bar, and returned by spring force. Adaptation to the necessary positioning forces is possible through different actuator sizes (diameters) and the number of return springs used. The following two valve actions are possible: Air to open / spring force to close and Air to close / spring force to open. The valve and the actuator need to be fitted with a positioner for controlling the position between 0... 100 %. The positioner and the diaphragm actuator form an integral unit. A follower pin allows for mechanical stroke measurement free of play. The point for stroke measurement is inside the yoke and protected by it. Therefore, this design complies with the regulations for the prevention of accidents. The air flow is guided through a channel bore inside the yoke.
