DP17 Carbon Steel Pilot Diaphragm Pressure Reducing Valve 2.5MPa 232°C for Steam Systems
The DP17 series pilot diaphragm type pressure reducing valve represents a significant advancement over conventional pressure reducing valves. Featuring innovative diaphragm materials and an expanded working area, this valve provides precise response to upstream pressure fluctuations and downstream load changes, ensuring exceptional downstream pressure stability.
Designed for steam system pipelines, this valve automatically regulates inlet steam pressure to maintain consistent outlet pressure using the energy of the steam medium itself. Suitable for industrial water, steam pipelines, fire water supply, municipal water systems, and various gas pipelines including air, nitrogen, oxygen, hydrogen, coal gas, liquefied petroleum gas, and natural gas.
