Product Overview
The proportional pressure
reducing valve produced by our factory has a beautiful appearance,
reliable quality, accurate proportion, stable operation, and can reduce
both dynamic and static pressure. This valve utilizes the pressure
difference generated by different cross-sectional areas of the piston
inside the valve body to change the pressure behind the valve and
achieve pressure reduction. The pressure reducing ratios of our
factory's pressure reducing valves are 2:1, 3:1, 4:1, 3:2, 5:2, etc.
Special proportion pressure reducing valves can also be designed
according to user requirements.YB43X fixed proportion pressure reducing valve is a regulating valve that proportionally reduces the pressure of the medium flowing through it. Usually used in high-rise buildings, pump stations, and fire protection systems, it can reduce both dynamic and static pressure, and has a reduced pressure ratio. The valve has a simple structure, excellent material selection, low price, and reliable performance. The proportional pressure reducing valve mainly consists of valve body, inlet flange, piston, large cylinder liner, small cylinder liner, outlet flange, O-ring, sealing gasket, and other parts. Proportional pressure reducing valve uses the different cross-sectional areas at both ends of the floating piston inside the valve to form the pressure difference between the front and back of the valve, and changes the pressure behind the valve to achieve pressure reduction.
