Product Description

Hydraulic Control Valve- Pressure Reducing Valve- Pressure Control Valve

Introduction
The pressure-reducing valve is adjusted to reduce the inlet pressure to a desired outlet pressure and rely on the energy of the medium itself to keep the outlet pressure automatically stable. From fluid mechanics point of view, pressure reducing valve is a throttling element, local resistance to change that by changing the throttling area, change the kinetic energy of the flow velocity and fluid, different pressure loss, so as to achieve the goal of decompression. Then the control and adjustment system can be adjusted to balance the pressure fluctuation of the valve and the spring force, so that the pressure of the valve remains constant within a certain margin of error. It is widely used in high rise buildings, water pressure of the city water supply pipe, and other occasions, so as to ensure the proper service water pressure and flow of water points in the water supply system.
