Tomoe Valve, a design and manufacturer of valves and process control systems, has announced a major extension to the G Series pneumatic actuator range. The extended G Series range now has 15 double acting and 15 spring return models and covers the Tomoe valve range from DN40 – DN600. Full traceability is available with each actuator, and a wide range of options are available including a stainless steel bodied actuator as well as a full range of other protective coatings. The G Series range of pneumatic actuators incorporates the unique Scotch Yoke design, using a 5 degree offset. This design enables the maximum torque to be delivered from the valve seat at closed position. The G series actuator range meets the latest ATEX requirements and is produced in an ISO 9001: 2000 factory. The G Series Scotch Yoke design also delivers a hysteresis figure of 1 to 2%. This combined with the G Series valve positioners with a hysterisis figure of 0.6%, produces a valve actuator package that is suited to many control valve applications.
