1.Pipeline Diameter: DN10～DN1000（mm)

2.Working Pressure: 0.6～32.0（MPa）

3.Aperture Ratio: 0.05≤β≤0.70

1.It is applied to the occasion where process materials needs to depressurize.

2.Large pressure drop is required in the upper and lower reaches of the valve in the pipeline, in order to reduce the erosion of the valve by fluid, when the flow through the orifice plate does not produce gas phase, the valve upstream series orifice plate can be used.

3.It is applied to the site where the fluid needs small flow and continuous flow, such as the flushing pipe of the pump, the bypass pipe of the hot standby pump (low flow protection pipe), the analytical sampling pipe and so on.

4.It is applied to the places where depressurization is required to reduce noise or wear, such as emptying systems.
