Which should be operated more gate or butterfly valves.
Which should be operated more gate or butterfly valves.
(OP)
I'm incharge of a valve maintenance program for a water distribution system. We go through the systems and operate every valve. My boss has asked me which valve should be operated more frequently, a gate valve or a butterfly valve. I can not find any data on this subject.





RE: Which should be operated more gate or butterfly valves.
My feeling is that if the gate valve has greased packing then I'd exercise the butterfly valves 4-5 times more often than the gate valve. If the stem packing in the gate valve has a tendency to fail through drying-out I'd cut that back to exercising the butterly 2-3 times more often.

RE: Which should be operated more gate or butterfly valves.
I have never had personal experience with a gate valve that does not leak, and crushing scale between the seats and disc will not contribute to improving the surface finish hence leak resistance of the valve.
