Overview:

Small diameter single-seat regulating valve can be used to control different pressure and temperature of fluid, the body in an s-shaped streamline channel, small pressure drop loss, large flow, adjustable range, flow characteristic of high precision, the regulator with more spring loaded diaphragm actuator, compact structure, big output force.

features

1. the percentage of features (log), percentage characteristics such as relative trip and no linear relationship between relative flow in the process of every point unit running change caused by the flow of change is proportional to the flow of this point, the percentage of the flow rate change is equal. So it has the advantage of traffic hours, changing flow is small, large flow, the flow rate change is big, is also on the different opening, has the same accuracy.

2 .linear characteristic (linear), linear characteristic of relative stroke and the relative flow into a linear relationship. Unit trip caused by the changes in the flow rate change is constant. Large flow, the flow relative changes little, traffic hours, flow relative change is big.

3 .a parabolic characteristics, flow according to the schedule of two proportional to change, with linear and roughly equal percentage in the middle of the properties.
