Operating principle of piston reducing valves
A reducing valve is an automatic valve which reduces the medium pressure to a certain value. There are two main kinds of reducing valves: piston reducing valves and spring diaphragm reducing valves. A piston reducing valve reduces pressure by means o…

What functions does a reducing valve have?
A reducing valve adjusts the medium flow by controlling the opening of the disc in the valve body so as to minimize the pressure. Meanwhile, it adjusts the opening of the disc by means of downstream pressure, so that the downstream pressure is kept wi…
