Carbon Steel Pilot Operated Diaphragm Type Pressure Reducing Valve For Steam Use
Product introduction:
DP17 series pilot diaphragm type pressure reducing valve has made significant improvements on the basis of ordinary pressure reducing valves. The diaphragm adopts new materials and greatly processes the working area, so subtle changes in upstream pressure or downstream load of the valve can be timely and accurately fed back to the main valve diaphragm to adjust the opening of the main valve and ensure the stability of downstream pressure.
DP17 series pilot diaphragm type pressure reducing valve used in steam system pipelines, which adjusts the inlet pressure of the steam pipeline to a certain required outlet pressure, and relies on the energy of the steam medium itself to automatically maintain stable outlet pressure. The outlet pressure of the main valve does not change due to changes in inlet pressure, nor does it change due to changes in the outlet flow rate of the main valve. It is suitable for industrial water and steam pipeline use, such as water supply, fire water supply, and domestic water pipe network systems and also used in gas pipelines, such as air, nitrogen, oxygen, hydrogen, coal gas, liquefied gas, natural gas, and other gases.

Product features:
1. It is an intelligent valve that uses the energy of the medium itself to regulate and control pipeline pressure.
2. Safety and reliable maintenance, the outlet pressure of the main valve can be adjusted by adjusting the pressure reducing pilot valve. The outlet pressure does not change due to changes in inlet pressure and flow rate.
3. Accurate pressure reduction effect, the set value can be adjusted as needed to achieve pressure reduction, stable performance, convenient installation and adjustment, and long service life.
4. Multiple pilot valves can be installed and exchanged on the same valve body, achieving temperature control, upstream pressure control, remote switch control, etc. while stabilizing the pressure.
