NORBAR'S VALVE TESTING SYSTEM HAS BEEN DESIGNED TO MONITOR AND CONTROL THE OPENING AND CLOSING OF BALL AND GATE VALVES BY MEANS OF TORQUE AND/OR ANGLE MEASUREMENT WITH OPTIONAL PROXIMITY SENSORS FOR ADDED SECURITY WHEN REQUIRED.
The power to rotate the valve can either be supplied via an AC Electric or Pneumatic Motor. This is connected to One of Norbar's tried and tested epicyclic gearboxes.
The size of gearbox is dependent of the torque required to operate the valve.
The gearbox is fitted with an Annular Transducer which is used to measure the torque being applied to the valve,this transducer can be fitted with an optional angle encoder to allow for positional control.
Norbar's systems allow differing levels of control from manual to fully automatic with cycling ability.
The ability to monitor or record BTO and BTC as well as running torque is present across the range.
