Product Name: Film type decompression regulator valve -water pressure reducing valve
Product Model: Y42X-16C
Product Class: Water reducing valve
Y42X series Spring diaphragm pressure reducing valve for water pressure control belong to direct action type film spring-loaded relief valves. Mainly by adjusting spring, diaphragm, piston, seat and disc etc parts. Using the diaphragm direct sensing downstream pressure drive disc, control valve disc opening voltage function complete decompression.
This product in city construction, high-rise buildings, hot water supply system could replace conventional division conduit, save equipment. Also can be in usually, up the pressure pipeline of cold voltage function.
This product surge voltage smooth, suitable for water movements, and the corrosive liquid medium piping.
Flange: RF FM RJ
Execution standard: JB79 GB/T 9113, ANSI B16.5
Reducing valve; Pressure reducing and sustaining valve
The pressure reducing valve is a pressure control valve which with throttle method make the outlet (downstream) pressure lower than the inlet (upstream) pressure, and keep the downstream pressure constant by reducing it to desired pressure, the desired pressure can be set according to the needs. The downstream pressure keeps constant and won't change by the upstream pressure changing or upstream flow rate changing.
Analyses them from the fluid mechanics point, the pressure reducing valve is a throttling element which local resistance is changeable. The reducing valve by changing the throttling area, change the kinetic energy of the flow velocity and fluid, produced different pressure loss, so as to achieve the goal of reducing pressure. And then through the adjustment of the control and regulation system, make the valve downstream pressure fluctuations and spring force keep equilibrium, the valve downstream pressure keep constant (no change or change within the error tolerances).
Tianjin U-ideal Instrument Co. Have Many different kinds of pressure reducing valve, such as: The piloted piston type pressure reducing valve, diaphragm pressure reducing valve, bellows type pressure reducing valve, proportional pressure reducing valve, self-reliance type pressure reducing valve, direct acting piston type pressure reducing valve, back pressure regulator, etc. They apply respectively to different working medium.
