Valve not shutting off due to lack of pressure?

I was working at a golf course today trying to stop a seeping valve. Tried replacing to top end and diaphram but no luck, still seeps. I know the body could have a crack or defect but let's assume it is ok. My question is it possible that the valve would not shut off due to lack of pressure? The system is run off of pumps that draw from a pond. It has many leaks and probably doesn't hold very much residual pressure. If this is the case do you have a solution?

Residential clean water valves were used which I know was not the best choice. If I do replace the valve what is your recommendation on dirty water valves?

Are these flow-control valves?

Rain Bird PESB which is the scrubber valve version of the PEB.

Treat the disease, not the symptoms........

Install a pressure gauge on the main to monitor the pressure loss and fix the leaks ArTurf. If the main is losing enough pressure to create the scenario that you've described you're going to have to find the source of the pressure loss and correct it.

I second that. The PEB / PESB is the best valve currently on the market. Period.

Sounds like you have a bad seat washer.

True.

But I'm just doing a little charity work, to fix it the way it needed to be "right" would be a major undertaking and they don't have the $$$ and I don't have the time.

Back to the original question. If there is not enough pressure to hold a valve closed there is no sense in replacing the valve.

Would different valves maybe perform better in this situation?
