Correlation Analysis of the Characteristics of Pilot Membrane Steam Pressure Reducing Valve

The pilot diaphragm steam pressure reducing valve is mainly suitable for pressure reducing occasions in steam main pipelines or process engineering, and can meet the requirement of maintaining constant downstream pressure, especially suitable for working conditions where the inlet pressure of the pressure reducing valve fluctuates or the steam flow rate changes sharply. The analysis of the relevant characteristics of the pilot membrane steam pressure reducing valve is as follows:

Features:

When the steam consumption changes sharply, the downstream pressure remains unchanged.

2. The upstream pressure fluctuates significantly, while the downstream pressure is not affected.

3. High precision, capable of controlling pressure within ± 0.2bar.

4. The maximum pressure reduction ratio can reach 20:1.

5. Convenient repair.

6. The ductile iron valve body material has stronger corrosion resistance and service life compared to cast iron for steam systems.

7. When no longer using steam, it is possible to maintain a stable downstream pressure at the set value.

8. Because the pilot diaphragm steam pressure reducing valve is a single spherical shape, its sealing performance is improved and the leakage is reduced.

Due to the large diaphragm area of the main valve and the use of an external sensing structure, it can stably control the outlet pressure.
