Advantages Of Electric Valves Over Traditional Valves

1. Packaging re-locked
If there is a slight leak at the packing, retighten the stem nut. But don't lock it too tightly, generally lock 1/4 turn to 1 turn, and it won't leak.
2. Replace the valve seat and seal
1) Disassembly
Put the valve in the half-open position, flush and remove possible dangerous substances inside and outside the valve, close the ball valve, remove the connecting bolts and nuts on the flanges on both sides, and then completely remove the valve from the pipeline. Disassemble the driving device in sequence - actuator, connecting bracket, lock washer, stem nut, butterfly shrapnel, Gram, wear plate, stem packing.
Remove the bonnet connecting bolts and nuts, separate the bonnet from the valve body, and remove the bonnet gasket. Make sure the ball valve is in the "closed" position. This makes it easier to remove it from the body and then remove the seat. Gently push the stem down through the body bore until it is all the way out, then remove the o-ring and lower stem packing. But be careful not to scratch the surface of the stem and the sealing part of the stuffing box of the valve body.
2) Reassemble
Clean and inspect disassembled parts. It is highly recommended to replace the seat and bonnet gaskets with a spare parts kit. Assemble in reverse order of disassembly. Cross-tighten the flange connection bolts to the specified torque. Tighten the stem nut to the specified torque.
After the actuator is installed, the corresponding signal is input, and the valve core is driven to rotate by rotating the valve stem to make the valve open and close. If possible, please carry out pressure sealing test and performance test on the valve according to relevant standards before reinstalling the pipeline.
