What are the main points of selecting valves?

First, clear the use of the valve. Determine the working conditions of the valve: the nature of the applicable medium, working pressure, working temperature and control mode.
Second, choose the right type of valve. Please consult technical personnel or engineers.
Third, determine the connection mode of the valve. For example, the most common ball valve is flange connection.
Fourth, choose the material of the valve, including the material of the body, internal parts and sealing surface, and so on. This needs to take into account the working conditions and the regulations of the relevant use department.

Welcome to purchase ball Valve manufactured by Yongjia Dalunwei Valve Co., Ltd. Ball valve is suitable for low temperature, high pressure, high viscosity media. Most ball valves can be used in media with suspended solid particles, and can also be used in powdery and granular media according to the material requirements of sealing;
The full-channel ball valve is not suitable for flow regulation, but it is suitable for occasions requiring quick opening and closing, which is easy to achieve emergency cutting; Ball valves are usually recommended in pipelines with strict sealing performance, wear, shrinking channels, rapid opening and closing action, high pressure cutoff (large pressure difference), low noise, gasification, small operating torque, and small fluid resistance.
Ball valve is suitable for light structure, low pressure cut-off, corrosive media; Ball valve or low temperature, cryogenic medium of the most ideal valve, low temperature medium piping system and device, should be selected with a low temperature ball valve cover;
When the floating ball valve is selected, the valve seat material should undertake the load of the ball and the working medium. The large-diameter ball valve needs a larger force during operation. The ball valve with DN≥200mm should use worm gear transmission form. Fixed ball valve is suitable for large diameter and high pressure occasions; In addition, the ball valve used for the process of highly toxic materials and combustible media pipelines should have a fireproof and anti-static structure.
