Problems associated with operating the control valve at a low opening degree
Thread Content
I would like to ask everyone: What are the hazards of operating a control valve at a low opening degree? And what exactly is considered a low opening degree – below what value does it qualify as such?
A small throttle gap results in high flow velocities and severe erosion, which damages the sealing surface of the valve core and significantly reduces the service life of the control valve. The control valve exhibits poor stability and may even experience severe oscillations； Control valves should be avoided from operating at low opening degrees; typically, the opening degree should be greater than 10~15%
It severely affects the service life of the control valve. The control valve has poor stability, and even severe oscillations can occur； * P5 o9 E5 l, A can be replaced with a small-bore control valve
