Direct acting spring diaphragm pressure reducing valve is a pressure reducing device that uses a diaphragm to directly sense downstream pressure changes to drive valve disc movement and automatically adjust opening. It achieves stable outlet pressure through dynamic balance between spring tension and fluid pressure.

Its core components only include regulating springs, diaphragms, pistons, and valve discs, with a simple and reliable structure, suitable for building cold and hot water supply systems and other pipelines, to prevent equipment damage caused by high water pressure and save energy and water.
