What is cast steel butterfly valve?

Cast steel butterfly valve is one kind of butterfly valve, whose valve body is mainly made of cast steel. The body material of cast steel butterfly valve is mainly divided into the following materials: cast steel, carbon steel, 20# steel, A182 steel, forged steel A105 F11 F22, chromium molybdenum steel WC6 WC9, stainless steel 304,316,etc; 

The nominal diameter of cast steel butterfly valve can be DN15-DN1200, the nominal pressure of cast steel butterfly valve can be PN1.0-50Mpa.

According to operating methods, there are manual lever cast steel butterfly valve, electrical cast steel butterfly valve, pneumatic cast steel butterfly valve, worm gear actuated cast steel butterfly valve;

The standard of cast steel butterfly valve can be: National Standard GB, American Standard API, ANSI, Japanese Standard JIS, German Standard DIN; 

According to end connections, cast steel butterfly valve has wafer type cast steel butterfly valve and flange type cast steel butterfly valve; 

Advantages of cast steel butterfly valve: 

① the cast steel butterfly valve has small size, and light weight, is easy to disassemble and maintain, and can be installed in any position; 

② the cast steel butterfly valve has simple and compact structure,small operating torque, and can achieve quick opening with rotating only 90°. 

③ the flow characteristics of cast steel butterfly valve tends to be straight, and the adjustment performance is good; 

④ the connection between the disc plate and the valve stem adopts a pinless structure, which overcomes the possible internal leakage point; 

⑤ the outer circle of the disc plate adopts a spherical shape, which improves the sealing performance and prolongs the service life of the cast steel butterfly valve, and the cast steel butterfly valve can be opened and closed for more than 50,000 times under pressure, and still maintain zero leakage; 

⑥ the sealing part of the cast steel butterfly valve can be replaced, and its sealing is reliable to achieve bidirectional sealing. 

⑦ the disc of the cast steel butterfly valve can be sprayed with coating according to user requirements, such a nylon or PTFE; 

⑧ the cast steel butterfly valve can be designed into flanged type cast steel butterfly valve and wafer type cast steel butterfly valve; 

⑨ the operating modes of cast steel butterfly valve have manual cast steel butterfly valve, electric cast steel butterfly valve and pneumatic cast steel butterfly valve; 

Cast steel butterfly valve is suitable for working temperature ≤425℃, and nominal pressure ≤1.6Mpa;
