Issues with high-pressure valve switching
Thread Content
It is very difficult to operate high-pressure valves (DN150 and above). Does anyone with expertise have any good methods or tools that they could share?
The handwheel’s? The handle’s? Make it longer.
A small valve can be placed next to the large valve; by opening the small valve, the pressure difference before and after the large valve can be eliminated, after which the large valve can be opened.
I’m sorry, I was foolish; I never asked
What pressure is generally considered high here? It gets complicated then. Thank you for your advice
Add a bypass line to the high-pressure valve and weld the valve
It is very difficult to operate high-pressure valves (DN150 and above). To address this issue, a drive mechanism consisting of a turbine or bevel gear is added to the valve. This should be specified explicitly when placing the order for the product; moreover, a bypass valve is installed during manufacturing in order to balance the pressure difference between the upstream and downstream sides when the valve is opened.
