Valve type and principle-Pressure reducing valve

The pressure reducing valve is an automatic valve that reduces the pressure of the medium to a certain value. Generally, the pressure after the valve is less than 50% of the pressure before the valve.There are many types of pressure reducing valves, mainly piston type and spring film type.

The piston type pressure reducing valve is a valve that is decompressed by the action of a piston.The spring diaphragm type pressure reducing valve relies on springs and membranes for pressure balance.
