SPA-R Pneumatic Quarter Turn Actuators Rack and Pinion SPA-R Pneumatic Actuators are suitable for easy, modular installation onto process control components such as Butterfly Valves, Cylindrical Plug Valves, Ball Valves or as operating device applied on automated Reactor Sampling Systems. Modular Design Actuators are available as double-acting or single-acting with spring return (fail safe close or fail safe open). Upon request, the actuators can be mounted onto valves as complete units, i.e. with solenoid valve, limit switch box or electro-pneumatic positioner, incl. all required mounting parts. Main Features • Robust design, body/cover made of cast aluminum, reliable function by proven rack and pinion construction Option: actuators with stainless steel bodies • Smooth surface finish of the cylinder bore (Ra 0.4-0.6 microns) for increased life span of actuator • Excellent corrosion protection of the actuator, resistant to salt spray for up to 500 hours • Easy replaceable guide pads made of materials with low coefficient of friction Standard Actuator with visual position indicator • Actuators with at least two bolt circles acc. to ISO 5211 for direct mounting onto valves • NAMUR interface for easy installation of limit switch boxes and solenoid pilot valves • Visual position indicator as integrated standard item • Special actuators, for extreme temperatures and any environmental conditions, upon specified request Conformity acc. to European Machinery Directive 2014/68/EU Actuator Unit On-Off with limit switch box and solenoid valve Actuator Control Unit with E/P positioner Subject to change w/o notic
