Pneumatic valve of choose and buy tips

when choosing the most suitable for your purposes of pneumatic valves should be careful. In order to avoid ambiguity, should make precise rules to each pneumatic valve, in the inquiry or order, for the pneumatic valve need to make comprehensive, appropriate instructions. What is the function, pneumatic control valve? Each pneumatic valve structure is used to perform certain functions. Don't count on a kind of pneumatic valve to perform all functions within the whole pipeline system. , pressure - Temperature rating. In order to satisfy the actual need, please pay special attention to the pneumatic pressure of the valve Temperature rating. It is important to pay special attention to the sealing material and liner material, these materials are quite extent, determines the pressure of the pneumatic valve - Temperature rating. According to the actual need to specify the sealing material and precipitation, to meet or exceed the actual demand. , pneumatic valve and connection mode. Pipeline system integrity, future maintenance, corrosion factors, field assembly, weight and safety factor are determined the pneumatic valve and pipeline connection factors should be considered. , operation mode, or operating methods according to the pneumatic valve type, size, pressure, temperature, installation environment factors such as the choice of appropriate operation mode or method of operation. Order, pneumatic valve, please provide the following data, avoid unnecessary again and again and delay, to ensure that the purchased pneumatic valve pneumatic valve is really what I need. Pneumatic valve size. Pressure boundary material: casting material and components. Pneumatic valve type: imported pneumatic ball valve pneumatic valve needle type pneumatic valve, globe pneumatic pneumatic valve, check valve, gate valve, pneumatic butterfly valve and so on. Terminal connection way, if the connection way for welding way, also provide a connection pipe wall thickness; If the connection is flange, should provide the flange surface or polishing. Any material that is different from the standard configuration: sealing materials, precipitation material, bolt material, and so on. Any accessories - acid shield, locking devices, chain operation, etc. Manual or power actuators, please include technical details of our requirements. For the purpose of order, please make sure the specifications. Must be identified with the nominal diameter of the pipe pneumatic valve connection. Pneumatic valve material in determining the correct valve material, should consider the following factors: · the pneumatic valve to control the fluid medium; , the temperature of the fluid medium range; To withstand the pressure range, pneumatic valves; Pneumatic valve, may affect the working conditions; Pneumatic valves are subjected to, possible abnormal pressure or stress; To meet safety standards, or plumbing codes.
