Gate Valve Turning

From Clow Valve Company's Resilient Wedge Gate Valve O & M Manual: "Frequency of inspection should be based on frequency of operation. Semi annual inspections are minimum recommended."

"During inspection, the valve should be opened and closed with pressure in the pipeline. The valve should function freely with no binding or vibration. Count the number of turns to full closed. This will reveal an obstruction if correct number of turns are not achieved. See table:"

Machine can be transported and used on the trailer hitch of a truck. The design of the unit helps prevent injuries as turning torque is applied to machine and not to the operator.

2" - 4.75
2.5" - 5.5
3" - 10
4" - 13.5
6" - 19.5
8" - 25.5
10" - 31.5
12" - 37.75

   
We also rent our valve turning equipment to cities and contractors if they would prefer to do the work themselves.

Properly maintained valves allow you to isolate and redirect water supply in the event of an emergency. Government agencies are now encouraging cities and rural water districts to perform regulare maintenance to be sure their systems are in good working order.

Valve exercising and regeneration are effective ways to protect your water supply system. We use the Hydra Turn torque limiting machine to exercise and regenerate your valves. We adjust the torque on our machine to minimize the possibility of damage. By using the machine, we have been able to regenerate many valves that have seized up or are hard to turn, thus saving costly repairs.

We compile and mail a complete list of valves and conditions to you after the service is provided.
