The 200X pilot operated pressure reducing valve is designed for high-rise buildings and is an ideal product for solving situations where large flow rates are required in the domestic and fire water systems of high-rise buildings. Its performance is good, replacing the intermediate water tank, saving the cost of building intermediate water tanks, and expanding the usable area of buildings.

Performance characteristics of 200X pilot operated pressure reducing valve:

1. Novel and reasonable structure, reasonable application of hydraulic principle control theory;

2. Stable and reliable work, with high traffic flow;

3. Fast opening and slow closing of valve disc, no water hammer impact (adjustable closing time);

4. Reduce and stabilize voltage, with a wide range of regulation;

5. Good sealing performance and long service life;

6. Easy installation and maintenance.

The 200X pilot operated pressure reducing valve is a valve that automatically maintains stable outlet pressure by adjusting the pressure to a desired outlet pressure and relying on the energy of the medium itself. From the perspective of fluid mechanics, a pressure reducing valve is a throttling element with variable local resistance. Pilot operated pressure reducing valves change the throttling area to alter the flow rate and kinetic energy of the fluid, resulting in different pressure losses and achieving the purpose of pressure reduction. Then, relying on the adjustment of the control and regulation system, the fluctuation of the pressure behind the valve is balanced with the spring force, keeping the pressure behind the valve constant within the error range.

Application principles of 200X pilot operated pressure reducing valve:

The pressure fluctuation of the 200X pilot operated pressure reducing valve should be controlled within 80% to 105% of the given pressure value. If it exceeds this range, the performance of the pressure reducing valve will be affected.

When the medium of the 200X pilot operated pressure reducing valve is air or water (liquid), it is generally recommended to use a direct acting diaphragm pressure reducing valve or a pilot operated diaphragm pressure reducing valve.

When the medium of the 200X pilot operated pressure reducing valve is steam, it is advisable to use a pilot operated pressure reducing valve or a pilot operated bellows pressure reducing valve.

For the convenience of operation, adjustment, and maintenance, pilot operated pressure reducing valves should generally be installed on horizontal pipelines.

Each spring of the pressure reducing valve is only applicable within the outlet pressure range, and the spring should be replaced if it exceeds the range.

Usually, the pressure Pc behind the pressure reducing valve should be less than 0.5 times the pressure in front of the valve, that is, Pc<; 0.5P1.

In situations where the working temperature of the medium is relatively high, pilot operated pressure reducing valves or pilot operated bellows pressure reducing valves are generally selected.

Installation requirements for 200X pilot operated pressure reducing valve:

1. It is recommended to install exhaust valves in the pipeline system to ensure stable operation of the pressure reducing valve.

2. During installation, attention should be paid to the direction indicated by the arrow on the valve body. For the convenience of maintenance and upkeep. Space should be left around the pressure reducing valve.

3. The import and export pressure should not be less than 0.2Mpa. If it is less than 0.2Mpa, the pressure stabilization performance will deteriorate (the outlet pressure error will increase).
