200x pressure reducing valve

200x pressure reducing valve

  • Product Type : Control Valve
  • Introduction : The product is the company's engineering and technical personnel with reference to the same type of advanced products at home and abroad to design and manufacture. The valve body adopts the whole channel streamlined design, the fluid resistance is small, the flow is large. Hydraulic operation is adopted in the rotation mode, that is, the water pressure in the pipeline is used to automatically operate the main valve flap to move up and down, control the valve port opening, adjust the downstream pressure, and maintain the downstream pressure at the pressure value set by the pilot valve spring. When the downstream pressure exceeds the set value, the pressure reducing valve will automatically close, regardless of how the inlet pressure P1 fluctuates, can output a stable outlet pressure P2. Regardless of changes in downstream flow, the outlet pressure P2 is maintained stable at the pilot valve set point. In short, the product is an ideal product for domestic water supply, fire fighting system and industrial water supply system.

Product Details

Structure type

The valve is composed of main valve, pilot valve, needle valve, check valve, ball valve, micro filter and pressure gauge. Since the pilot valve, needle valve and pressure gauge are connected to the main valve with a catheter, they are collectively referred to as the catheter control system, as shown in the figure.
