Technical Specification Sheet Document No. A6V11858963 July 26, 2021 Siemens Industry, Inc. Page 1 of 10 Resilient Seat Butterfly Valves Description Designed to last longer with minimal downtime, Siemens resilient seat butterfly valves are available in sizes from 2 to 24 inches (DN 50 to 600) built with the highest temperature and chemical resistance available in the market. Available in 2-way and 3-way configurations, 2” through 20” butterfly valves are lug style. 24” valves are double-flanged. All have ANSI 125 rated bodies. 3- way valves can be used for mixing and diverting applications and are available in multiple configurations to match job site needs. These valves are compatible with Siemens A-Series Industrial Electric, and OpenAir ® Commercial Electric actuators. OpenAir actuators are available in in both spring return and non-spring return variants for two- position (On/Off), Floating and Modulating control. All Industrial actuators include a heater to prevent condensation. Resilient seat butterfly valves provide bubble-tight shut off (leakage class better than ANSI Class VI) up to 175 PSI (Full Cut) and 50 PSI (Under Cut) requirements. Application Siemens Resilient Seat butterfly valves are suitable for standard temperature (intermittent 250°F) or high temperature applications (continuous 250°F). Standard temperature assemblies can be field upgraded to high temperature at any time by updating the actuator. There is no need to remove the valve from the piping. These valves can be used for isolation purposes or as modulating valves. Siemens butterfly valves are optimized for use in Chilled Water, Hot Water and Open Loop Cooling Tower applications. Features • High purity, peroxide cured, high temperature EPDM seats to ensure continuous operation at 250°F (121°C) • Corrosion-resistant, 316 Stainless Steel disc (2” through 12”) • Corrosion-resistant Electroless Nickel Plated Ductile Iron (14” through 24”) • Internal disc-to-stem connection to eliminate leakage through the stem • Wide variety of direct mount actuators. • Full 175 PSI and 50 PSI close-off pressure ratings available.

Determine the designed Cv as follows: Q = Flow in gallons per minute (GPM) required to pass through the valve SG = Specific gravity of the fluid (water = 1) ∆P = Designed pressure drop across the valve in PSI Cv = Flow coefficient NOTE: For modulating butterfly valves, size for design flow at 60° rotation. 2. Determine if the valve should be line sized or sized to match the designed pressure drop: Option 1: On/Off Valves Select the valve size to equal the pipe size Option 2: Modulating Valves Size the valve for design flow at 60° open 3. Determine actual pressure drop as follows: Pressure drop is recommended to be no higher than 29 PSI or match the designed pressure drop. For modulating applications 3, 4, 5, and 6 PSI are commonly accepted. 4. Ensure that close-off requirements are met. Page 4 of 10 Siemens Industry, Inc. Actuator Product Numbers Table 2.
