Industrial ST90 Pneumatic Valve Actuator

Industrial ST90 Pneumatic Valve Actuator from Sonic Torque, a division of Sharon Piping, delivers precise 90° valve rotation for sanitary CF3M process equipment. The ST90 is a quarter-turn pneumatic actuator designed to operate Sharpe CF3M sanitary valves, with documented pairings including 2" and 3" valve sizes and a maximum supply pressure of 120 psi (8 bar). It is built for clean-in-place and hygienic lines, with mounting compatibility to ISO 5211 and DIN 3337 patterns to simplify installation on valve bodies. The SPN-series documentation confirms a 90° actuator stroke for this family, underscoring its role in typical 90° valve applications. NAMUR interface options are available on select configurations, enabling integration with standard automation accessories. This actuator is compact and robust, intended for reliable, repeatable open/close cycles in sanitary processing environments, and is commonly paired with Sharpe CF3M ball valves in stainless sanitary systems.
