Description for Kieselmann 511X S-S KI-DS Control Valve Diaphragm Actuator

Exact process control KIESELMANN control valves for liquids and gases regulate volume flows and pressures in process plants. The selection of the appropriate valve type depends on the application. The space-saving and cost-effective butterfly valves with positioners are ideal for simple control tasks. For processes requiring high control accuracy, KI-DS single-seat control valves are the right choice Butterfly valves with positioner: Space saving, cost-effective Butterfly valves with positioner are the cost-effective solution for simple control tasks in piping systems. The valve is actuated and regulated by a digital electro-pneumatic positioner. The positioner, actuator and valve form a closed control loop. A detailed description of the positioner can be found here. Single-seat control valves: Highly precise and modular The versatile, hygienic single-seat control valves from KIESELMANN are available in linear and equal-percentage versions. They are based on our proven KI-DS valve concept and are suitable for sensitive production areas in the food and beverage industry. The modular design with the large nominal diameter range from DN 25 to DN 125 and the functionally graded flow coefficients offers maximum flexibility - and the right valve for every application. High control accuracy and cavitation resistance A major advantage of our control valves is the replaceable cone and valve seat. If the process conditions change, KIESELMANN control valves can be adapted quickly and easily - without having to replace the complete valve. Within a nominal diameter, the valves can be converted at any time to different flow coefficients, control characteristics and seal types. With nominal pressures of up to PN 16 as well as metallic and elastomeric sealing concepts, the valves enable safe and precise process control and sealing. Electropneumatic positioner Positioners with M12 round plug and Bluetooth and USB interface are available for all control valve types. The setting of the control range can be made in the higher-level control. It is even more convenient via the Bluetooth interface. This makes it possible to configure the valve directly on site with a tablet or smartphone. This is possible even if the valve is installed difficult to reach. This ensures the direct access to the process that many users have requested. • Three actuators with compatible connections • Maintenance-free actuator with 5 years warranty • Maintenance-friendly intermediate flange design • Cost-effective • Modularity • Simple adaptation • Flexible cone & replacement seat concept • Elastomer sealing or metallic sealing • Linear or equal-percentage control Technical data Sizes: DN 15–120, 1"–4" Seals: EPDM HNBR FKM        SIP 140°C, 30 min                                          SIP 110°C, 30 min                                          SIP 95°C, 30 min Kv values: 0.4 – 160 m³/h Materials: in product contact     1.4404 / AISI 316L                                   1.4542 / AISI 630                                   17-4PH Product-contacting surfaces : Ra ? 0.8 µm e-polished Actuator: - Diaphragm actuator - Lifting piston actuator Operating pressure: PN 16 Control air: 5.5-8 bar lower control air pressures on request Operating temperature: 95 °C
