    The pressure reducing valve is a valve that reduces the inlet pressure to a certain required outlet pressure through adjustment, and relies on the energy of the medium itself to automatically maintain a stable outlet pressure. From the point of view of fluid mechanics, the pressure reducing valve is a throttling element whose local resistance can be changed, that is, by changing the throttling area, the flow rate and the kinetic energy of the fluid are changed, resulting in different pressure losses, so as to achieve the purpose of pressure reduction. Then rely on the adjustment of the control and regulation system to balance the fluctuation of the pressure behind the valve with the spring force, so that the pressure behind the valve remains constant within a certain error range.

    product description

    The pressure reducing valve reduces the water pressure by the local resistance of the flow passage in the valve to the water flow. The range of the water pressure drop is automatically adjusted by the diaphragm connecting the valve flap or the water pressure difference between the inlet and outlet on both sides of the piston. The principle of constant ratio pressure reduction is to use the water pressure ratio of the floating piston in the valve body to control. The pressure reduction ratio at the inlet and outlet ends is inversely proportional to the piston area ratio at the inlet and outlet sides. This kind of pressure reducing valve works smoothly without vibration; there is no spring in the valve body, so there is no concern about spring corrosion and metal fatigue failure; the sealing performance is good and does not leak, so it reduces both dynamic pressure (when water flows) and static pressure (flow rate is 0 o'clock); especially when decompression does not affect the water flow.
