What is the purpose of the hole on the side of the diaphragm valve?
Thread Content
I would like to ask everyone about the valves on the demineralized water pipelines in my factory.
Through-diaphragm valve with back exhaust to prevent pressure buildup
Thank you! Do you mean the back side as in above the diaphragm?
Is water coming out of this hole now? Is the diaphragm broken?
This is called a leak detection hole; it allows you to know if there is a leak! Replace the diaphragm in a timely manner
Yes, replace it as soon as possible. The diaphragm of a diaphragm valve is a consumable part that needs to be replaced and maintained regularly
