Pressure reducing valve

The pressure reducing valve is an automatic valve that reduces the medium pressure to a certain value. Generally, the post-valve pressure is less than 50% of the pre-valve pressure. 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.
