We are a valve manufacturer, and Forged Steel Gate Valves API602 is one of our products. Let me share with you the selection points and installation matters of Butterfly Valves.

　　Selection points

　　1. The main control parameter of butterfly valve is size.

　　2. The butterfly valve is a single-plate air valve, which is simple in structure, convenient in processing, low in cost and easy in operation, but has poor adjustment accuracy and is only suitable for on-off or rough adjustment in ventilation and air-conditioning systems.

　　3. It can be operated manually, electrically or by zipper, and can be fixed at any angle within the range of 90°.

　　4. Due to the single shaft and single valve plate, the bearing capacity is limited, and the service life of the valve is short under the conditions of large pressure difference and large flow rate. The valve is divided into closed type and ordinary type, thermal insulation and non-thermal insulation.

　　5. The electric butterfly valve has only two-position control, and the electric actuator is the same as that of the multi-leaf valve.

　　Installation matters

　　Butterfly valve has simple structure, small volume, light weight, and its components are relatively small. Only a few key parts can constitute a butterfly valve, and it is very convenient to open it. You only need to select the switch to 90 degrees. The control of the fluid is very good, and the flow can be increased or decreased at any time. The valve has a certain resistance when transporting any fluid, and the resistance of the butterfly valve mainly comes from itself, such as the thickness of the butterfly valve body. The resistance just needs to be reduced in its thickness.

　　Elastomeric seals have the disadvantage of being limited by temperature.

　　Butterfly valves have a wide range of applications. If they are used to control flow, you need to choose different types and sizes of valve bodies, because butterfly valves are more suitable for valves with larger diameters when they are designed. Butterfly valves are not only widely used in general industries such as petroleum, gas, chemical, water treatment, etc., but also in the cooling water system of thermal power plants.
