200X diaphragm-type reducing valves
Structure and function
200X pressure-reducing-and-maintaining valve is hydraulic control taking-over system consisting of main valve,pilot valve, needle valve, ball valve, mini-filter and pressure gauge.When using,it can automatically keep stable outlet pressure after it has been fixed.
This product make use of self-reliance control of pilot valve, without any other device or energy, easy to maintain, high accurate pressure control, small influence by inlet pressure and flowrate, pressure-reducing-and-maintaining is reliable.Widely used in high-rise buildings and life water supply.
