What Are The Factors Affecting The Service Life Of Sanitary Diaphragm Valves?

Sanitary Diaphragm Valve is a stop valve that uses a diaphragm as a start and close member to close the flow channel, cut off the fluid, and separate the inner cavity of the valve body from the inner cavity of the valve cover. The diaphragm is usually made of elastic, corrosion-resistant, and non-permeable materials such as rubber and plastic. So do you know what factors affect the service life of sanitary diaphragm valves?

The factors affecting the service life of sanitary diaphragm valves are introduced as follows:

1. The method of increasing the working opening of sanitary diaphragm valves to increase the service life

The sanitary diaphragm valve increases the loss of the system except the sanitary diaphragm valve, which reduces the pressure drop allocated to the valve. In order to ensure that the flow passes through the sanitary diaphragm valve, the opening of the sanitary diaphragm valve must be increased. At the same time, the pressure drop on the valve is reduced, and cavitation and erosion are also weakened.

2. The method of extending the service life of sanitary diaphragm valves by working at a large opening
Let the sanitary diaphragm valve work at a large opening as much as possible from the beginning, such as 90%. In this way, damage such as cavitation and erosion occurs on the valve core head. As the valve core is damaged, the flow rate increases, and the corresponding valve is closed a little more. In this way, it is continuously damaged and gradually closed, so that the entire valve core is fully utilized until the valve core root and sealing surface are damaged.
The orifice plate throttling consumes the pressure drop after the sanitary diaphragm valve; close the manual valve in series on the pipeline until the sanitary diaphragm valve obtains a more ideal working opening.
