Self-reliance type regulator is a new regulator type. Compared with the manual control valve, its advantage is to largely type regulator; Relative to the electric control valve, its advantage is not need external motivation. Sealing performance and strength are all self-reliance type regulator is the most basic, the most important performance.

Self-reliance type regulator is a new regulator type. Compared with the manual control valve, its advantage is to largely type regulator; Relative to the electric control valve, its advantage is not need external motivation. Sealing performance and strength are all self-reliance type regulator is the most basic, the most important performance.

Self-reliance of the regulating valve sealing part sealing and the outer seal. The sealing between disc and seat sealing; Seal is between moving parts and valve cover, stem between valve body and valve cover and seal between the valve and pipeline connection parts. Self-reliance type regulator when use not only requires good seal performance, and must ensure safety.

If because of the bad sealing leakage or damage due to insufficient strength and make the parts, will lead to different degree of economic losses, such as toxic, flammable and explosive or corrosive liquid, can also lead to serious safety accidents. To ensure self-reliance type valve seal and strength, in addition to comply with the requirements of the relevant standards must be reasonably for structural design, ensure the quality of the process, must also be correctly chosen materials.
