You should understand this point of pneumatic high-temperature small caliber ball valve
Small caliber pneumatic high temperature ball valve is widely used in the laboratory, which requires comparison of data. Therefore, valve selection is particularly important. At this time, we should pay more attention to the selection. The traditional rack type pneumatic high temperature small caliber ball valve is bulky and bulky, and its opening and closing angles are single, so it is difficult to get accurate data.

What are the types of stainless steel gold bellows?
From the planning point of view, the metal bellows have two kinds of materials, strip and pipe, which can form annular bellows and spiral bellows.
The annular corrugated pipe is a pipe with special shapes whose outer edge of a number of annular diaphragms is tangent to a number of concave centripetal semicircular rings, and the inner edge is tangent to a number of concave vest semicircular rings. Its blank is mainly pipe material. This type of corrugated pipe has the following characteristics: large flexibility, good elasticity, simple manufacturing and small rigidity. It is suitable for manufacturing pneumatic butterfly valves with large and medium diameters that bear normal working pressure and have high demand for flexibility.
Spiral corrugated pipe is a pipe with special shapes whose outer edge of the spring wound membrane of a certain length is tangent to the spring wound concave centripetal semicircular ring, and the inner edge is tangent to the spring wound concave vest semicircular ring.
This type of bellows has the characteristics of high strength, high rigidity, simple manufacturing, etc., and is suitable for making pneumatic butterfly valves with high and medium pressure, medium and small diameters that have common flexible requirements and high strength requirements.
