Overview of proportional pressure reducing valve

The proportional pressure reducing valve has beautiful appearance, reliable quality, accurate ratio, stable operation, and reduces both dynamic pressure and static pressure. The valve uses the pressure difference generated by the different cross-sectional areas of the piston inside the valve body to change the pressure after the valve to achieve the purpose of reducing pressure. The pressure reducing ratio of the pressure reducing valve is: 2:1, 3:1, 4:1, 3:2, 5:2, etc. The pressure reducing valve with a special ratio can also be designed according to the requirements of users.

Main technical parameters of fixed proportional pressure reducing valve

Main dimensions of fixed proportional pressure reducing valve

Flange connection size PN1.0MPa according to GB4216.4-84 standard, PN1.6MPa according to GB4213.5-84 standard

Y43X-10, Y43X-16 cast iron proportional pressure reducing valve: flange connection type, piston type structure, seat sealing surface material is rubber, nominal pressure PN10~PN16, valve body material is cast iron fixed proportional pressure reducing valve valve.

The main structure is composed of valve body, inlet gland, piston, outlet gland, O-ring, gasket and other parts. The Y43X-10, Y43X-16 cast iron proportional pressure reducing valve uses the different cross-sectional areas of the floating piston in the valve to form a pressure difference to change the pressure of the inlet and outlet water to achieve the purpose of reducing pressure.
