Why can't the dimension of pneumatic vertical butterfly valve d973w be rotated? The hole of the O-ring butterfly valve is a straight hole that runs through the world. When the valve core rotates, the area of the orifice changes. Its characteristics are as follows. 1. The flow characteristics are approximately quick opening characteristics. Therefore, the O-ring butterfly valve is often used as a cut-off control valve containing fiber, slurry or viscous fluid. Its operating temperature is not more than 200 ℃, and its operating pressure is not more than 0.1MPa.
2. The valve body is symmetrical, the flow direction of the fluid can be arbitrary, and the rotation angle of the valve core can be one-way or two-way from 0 ° to 90 ° With simple structure and convenient maintenance, soft sealing can be used. Because of reliable sealing and small leakage, soft sealing O-ring butterfly valve (PTFE seat) can reach bubble level sealing. 4. High adjustable ratio. Usually, it is connected with the piston? Type actuator or fully electronic actuator can be used together, and the adjustable ratio can reach 100:1 - 500:1. 5. The price is much higher than that of ordinary butterfly valves. V-shaped butterfly valve is a butterfly valve with a V-shaped notch on the spherical valve core. The shape of the notch is related to the flow characteristics of the control valve.
、 The small and light pneumatic butterfly valve is very smooth both in its use and installation. When you really have a very reasonable understanding of these smooth, you can better ensure that your overall installation work is very smooth. We can install according to the correct requirements after we understand this in time. Are you clear about this?
