Where is the local switch for pid control of electric low load regulating butterfly valve? Generally, when using an electric valve, we expect it to have a relatively long service life and repair free period, which depends on its normal operating conditions, maintaining a harmonious temperature/pressure ratio, reasonable corrosion data and other factors.
、 If a pipe filter is installed in the front section of the valve, it is also a good method to prevent blocking, especially for the valve with ultra small flow, the effect is more prominent. In addition, we can start from changing the valve structure, such as using throttling parts with large throttling clearance.
