Series Description

Designed to last longer with minimal downtime, Siemens resilient seat butterfly valves are available in sizes from 2 in. to 24 in. (DN 50 to 600). They are built with the highest temperature and chemical resistance available in the market.Available in 2-way and 3-way configurations, 2 in. through 20 in. butterfly valves are lug style. 24-in. 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 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.
