1、Compact structure --- the built-in spring structure makes the pressure regulating valve more compact, and has better protection.
2、No packing----with the control of the micro pressure, any friction resistance will impact the accuracy of pressure regulating valve. The valve without packing structure allows good sensitivity of the pressure structure, and reduces the leakage point.
3、Thrust amplification----micro pressure control valve has limited tension generated by the executional mechanism for the low control pressure. Pressure regulating valve magnify the small force generated by the diaphragm assembly 6 times with the lever force amplification mechanism of regulating valve to achieve good adjustment property and pressure resistance. In the same time, downstream flow is reduced to "0", and the valve core can turn off fluid in micro-pressure state, preserving the pressure of the system.
4、valve factory cannot predict the field piping and installation space, so it is often found that due to the peripheral equipment, the pressure adjusting valve adjustment is affected and hard to observe after installation. SP439 pressure valve actuator together with the regulating mechanism can do 360-degree rotation in the non-disintegration state, the original performance parameters are not affected after adjustment.
5、The clip connection form saves space to reduce costs.
