1 TOPQUALITY PNEUMATIC ACTUATOR BS EN ISO 9001:2000

2 INTRODUCTION PDS series Pneumatic Actuars are designed using ScotchYoke technology from PDS 50 the largest of PDS 200. ScotchYoke technology is well known all users as the most suitable actuar mechanism for valve and damper operation as it produces higher rque at both end positions. Specification of PDS actuars follow international standards for faster and easier mounting of accessories like Solenoid valves, limit switches, positioners etc. ITORK Controls Ltd. also provides ITS series limit switch boxes (weather proof, explosion proof), solenoid valves, positioners for modulating services and other pneumatic accessories. Side handwheel and declutchable gear box for manual operation are also options available in the ITORK product range. Ranges available are 10Nm through 000Nm double acting, and 5Nm through 1900Nm spring return. The range of ambient temperature for standard operation is 20 o C~ 80 o C as standard (For higher and lower temperature applications please consult manufacturer before placing order). Mounting dimensions follow ISO5211, DIN3337, NAMUR, VDI/VDE385 standards, The drive shafts come in various sizes with double square shaped female bore for accomodating valve shaft, package is precompressed for increased safety, Extremely long service life and reliable performance. 2
