Pneumatic valve actuator A series

rotarydouble-actingsingle-acting with return spring

Overview
UniTorq A-Series pneumatic actuators are designed for demanding industrial applications. The actuators feature a cast 304 or 316 stainless steel body and are available in multiple sizes (A10, A30, A73, A148, A295, A470, A586, A1213). Configurations include double-acting and spring-return variants. Stainless steel solenoid valves are offered to complete solutions for corrosive environments.

Applications / Environments

• Chemical processing and manufacturing
• Coastal and marine installations
• Food & beverage production
• Pharmaceutical manufacturing and facilities handling caustic materials

Performance and torque data
