Characteristics

The 200X pressure reducing valve is a functional valve that regulates and controls the pipeline pressure by using the energy of the medium itself. The outlet pressure of the main valve can be adjusted by adjusting the relief pilot valve. The outlet pressure does not change due to the change of inlet pressure and inlet flow. The outlet pressure is safely and reliably maintained at the set value, and the set value can be adjusted according to the need to achieve the purpose of pressure reduction. The valve features accurate pressure reduction, stable performance, safety and reliability, convenient installation and long service life.

Key Advantages
  • 1. Reliable sealing and long service life

    The main valve of the 200X relief pressure valve adopts rubber diaphragm+soft seal structure, with good sealing performance, not easy to leak, and reduce water waste.

    The valve body is mostly made of nodular cast iron/steel, with high strength, water pressure resistance, wear resistance and long service life.

  • 2. With filtration and monitoring, low maintenance cost

    Microfilters are standard to prevent foreign matter from seizing the pilot valve, reduce failures, and extend service life.

    The pressure gauge can be equipped to visually monitor the inlet and outlet pressure for the convenience of commissioning, patrol inspection and troubleshooting.

    Easy to disassemble and clean, easy to replace vulnerable parts (diaphragm, spring and sealing parts), simple maintenance and low cost.

Frequently Asked Questions (FAQ)
What is the main function of the 200X pressure reducing valve?
The 200X pressure reducing valve automatically reduces higher inlet pressure to a steady lower outlet pressure regardless of flow rate or inlet pressure fluctuations, using the medium's own energy.
How do you adjust the outlet pressure value?
The target outlet pressure can be easily set and adjusted by regulating the relief pilot valve mounted on the top of the main valve assembly.
Where is the 200X hydraulic control valve typically installed?
It is widely applied in high-rise building water supply networks, municipal water systems, residential pipe networks, and fire protection systems that require precise pressure stabilization.
How does the valve prevent clogging from impurities?
Microfilters are included as standard components to prevent foreign matter from entering and seizing the pilot valve, significantly reducing maintenance frequency.
What body materials are available for this valve?
The body is available in Ductile Iron, Cast Steel, and Stainless Steel to accommodate different medium types and working environment demands.
