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