Our Products #802970

PGD PGS series are the pneumaticactuators designed using a scotch-yoketechnology from PGD PGS 50 to 200.Scotch-yoke technology is well-knownas the most suitable actuatormechanism for valve and damperoperation because it can produce ahigher torque at both end positions.All specifications follow internationalstandards to mount the valveaccessories like solenoid valves, limitswitches, valve positioners.Torque is available from 10Nmthrough 4000Nm double acting andfrom 5Nm through 1900Nm springreturn.The operating ambient temperaturerange is -20oC +80oC as standard(For higher and lower temperatureapplications, please contact us beforeplacing order).Mounting dimensions followstandards of ISO5211, DIN3337, NAMUR and VDIVDE3845. The driveshafts can be provided in various sizeswith double square shaped female boreto accomodate valve shaft. Springpackage is pre-compressed for safety.Extremely long service life and reliableperformance.POWER-GENEX Ltd. also providesLSB series limit switch boxes (weatherproof, explosion proof), solenoid valvesand valve positioners. Side hand-wheeland de-clutchable gear box for manualoperation are also optionally available.
