603 series valve gear-box can provide a reliable position control of gate, stop valves, as well as similar ones. When combining with multi-turn electric actuators, 603 series can be used as electric ones.
Characteristic
High strength:
Adoption of high grade steel gears, copper alloy stem nut and grey cast iron house provides 603 series high strength.
Reliable sealing:
All units fully O-ringed sealed and permanently lubricated with molybdenum disulfide grease.
High efficiency:
Thrust bearings are mounted in both sides of the stem nut.
603P type with mechanical indicator can continuous indicate the valve position. It can feed back the position signal of valve if need.
Two output drive types of plug sleeve and stem nut which can bear thrust are available to connect with the valve.
