Top 10 safety valve core Manufacturers in China

Introduction to Safety Valve Core

A safety valve core is a crucial component in various industrial systems, especially in hydraulic, pneumatic, and pressure - related applications. Its main function is to ensure the safety of the system by controlling the pressure within a safe range. When the pressure in the system exceeds the preset value, the safety valve core will open to release the excess pressure, preventing equipment damage, explosions, or other dangerous situations. Safety valve cores come in different types, such as direct - acting, pilot - operated, and spring - loaded, each suitable for different working conditions and pressure requirements.
