Pneumatic valve in the industrial process, mostly used to control the movement and flow of various fluids, such as water, oil, chemical liquids, etc., based on the parameters of temperature, pressure and flow. Aske machinery to look at the market for modern factories commonly used control valves have pneumatic film regulator valve, pneumatic ball valve, pneumatic butterfly valve, pneumatic diaphragm valve and other types of efforts to create a more beautiful, durable pneumatic valve. In the selection of various automatic valves in modern factories, we should consider the type of heat engine, the accuracy of the requirements, the quality of the control valve, pressure drop, flow and its structure, failure rate, manufacturer credit and after-sales service and other factors, in order to achieve the purpose of economic and practical. Pneumatic valve itself has the advantages of easy assembly, low failure rate, and in line with the needs of industry automation, easy installation can save other costs to make the enterprise more competitive and vitality.
