Plastic Butterfly Valve

The plastic butterfly valve is a kind of valve that uses the circular butterfly plate as the opening and closing part and rotates with the valve stem to open, close and adjust the fluid channel. The butterfly valve disc is installed in the diameter direction of the pipeline, in the butterfly valve body cylindrical channel, the disc disc rotates around the axis, the rotation Angle is between 0°~90°, when the rotation to 90°, the valve is in a fully open state. The body structure of plastic butterfly valves is usually centre-line and matched with standard convex pipe flanges.

• Strong corrosion resistance: Key components such as the valve body and valve plate of plastic butterfly valves are usually made of high-performance engineering plastics, such as PVC, PP, CPVC, PVDF, PTFE, etc. These materials

• Excellent corrosion resistance, can resist a variety of acid, alkali, salt and other corrosive media erosion.

• Wear resistance: The material and process of the plastic butterfly valve make it have good wear resistance, can withstand high temperature, high pressure and other harsh conditions, and extend the service life.

• Good sealing performance: plastic butterfly valves usually use soft sealing or hard sealing structure, which can ensure a tight fit between the valve and the pipeline when the valve is closed, effectively preventing media leakage.

• Strong flow capacity: The plastic butterfly valve has a great flow capacity, and the pressure loss through the valve is minimal, which is suitable for the pipeline system that requires large flow.

• Good economic performance: The plastic butterfly valve body has a very significant economy, especially the larger caliber butterfly valve, compared with other types of valves, its price is more affordable.
