Proportional pressure reducing valve product introduction
Products: ◠Hydraulic principle control, simple structure ◠Accurate decompression ratio, large flow passage ◠Reduced pressure and static pressure ◠Smooth operation No noise, no vibration, water hammer reduction, protection of pipe network ◠Suitable for Installation at any angle ◠Light weight, small size, easy installation and maintenance Working principle: Under the action of inlet pressure P1, the floating piston is pushed open and the medium passes. Due to the cross-sectional area of ​​the piston at both ends of the pressure difference caused by changes in the pressure after the valve, that is, the pressure in the pipeline case, the ratio of the area of ​​the piston at both ends of the valve before and after the composition of the pressure ratio. No matter how the pressure changes before the valve, the static pressure and dynamic pressure after the valve can be reduced to the corresponding pressure value.
