1 TOP-QUALITY PNEUMATIC ACTUATOR BS EN ISO 9001:2000

2 INTRODUCTION PDS series Pneumatic Actuators are designed using Scotch-Yoke technology from PDS 50 to the largest of PDS 200. Scotch-Yoke technology is well known to all users as the most suitable for valve and damper operation as it produces higher torque at both end positions. Specification of PDS actuators follow international standards for faster and easier mounting of accessories like Solenoid valves, limit switches, positioners etc. I-TORK Controls Ltd. also provides ITS series limit switch boxes (weather proof, explosion proof), solenoid valves, positioners for modulating services and other pneumatic components. Side hand-wheel and de-clutchable gear box for manual operation are also options in the I-TORK product range. Ranges available are 10Nm through 000Nm double acting, and 5Nm through 1900Nm spring return. Max. operating temperature is -2 C~ 8 C as standard (For higher and lower temperature applications please consult manufacturer before placing order). Mounting dimensions follow ISO5211, DIN3337, NAMUR, VDI/VDE385, Drive shaft with various sizes and shaped female bore for valve shaft, package pre-compressed for increased safety, Extremely long service life and reliable performance. 2
