Product Details

Overview

The high-temperature and high-pressure main safety valve is suitable for steam pipelines with a working temperature of ≤ 425 ℃. The main safety valve should be used in conjunction with the impulse safety valve to open the main safety valve through the impulse safety valve opening pressure signal, and then fully discharge; When the pressure drops to the specified value, the main safety valve automatically closes, which is a supporting equipment in the temperature and pressure reducing device commonly used in modern energy-saving engineering. Widely used in industries such as cogeneration, light textile, petrochemical, sugar making, etc. to ensure the safe operation of equipment.
