Pneumatic diaphragm regulating valve handwheel is how to work
Pneumatic diaphragm regulating valve handwheel is how to work the function of the pneumatic control valve handwheel is bigger. Handwheel institutions and regulating valve, main use is as follows: 1, when the source signals, or signals fails, or when the actuators are the main components, such as diaphragm, spring, sealing parts and transmission parts damage, to automatically instead of manual operation, can use the handwheel institutions continue to adjust the regulating function of the valve. 2, the handwheel institutions can also be used as a regulating valve stroke limiter. 3, the handwheel institutions can improve the reliability of valve operation adjustment. Adjust such as adding bypass valve, investment costs more, covers an area of big, when the diameter is larger or more expensive when using precious metals. Using the handwheel organisations in investment costs and covers an area of consideration, it is cheaper.
