Technical Instructions Document No. A6V11858954 September 8, 2020 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. A-Series actuators are fail-in-place and available for two-position (On/Off) and Modulating control. OpenAir actuators are available in both spring return and non-spring return variants for two-position (On/Off), Floating and Modulating control. 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. 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. 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. Caution and Warning Notations WARNING: Personal injury or loss of life may occur if you do not perform a procedure as specified. CAUTION: Equipment damage may occur if you do not perform a procedure as specified. Product Numbers See Table 6.

Time-Out Function To prolong Commercial actuator life when using Floating Control (3 Point), a controller with a “time-out” function must be used. This function removes the actuator drive signal after the signal has been on for a pre-defined time.
