PVC Butterfly Valve

PVC Butterfly Valve is a butterfly valve made of PVC material, which is used to control the flow and pressure of the fluid. Its working principle is to adjust the position of the valve disc by rotating the valve shaft, thereby controlling the flow and pressure of the fluid.

JUNRUI Industry can supply various sizes PVC Solvent Cement Joint fittings from DN20mm to DN400mm.

PVC Solvent Cement Joint fittings include: equal tee, reducer tee, reducer, elbow 45 degrees, Elbow 90 degrees and so on. Can be customized according to requirements, our PVC fittings are high quality new and unused Polyvinyl chloride raw materials, mainly used in PVC water, drainage and cable protective systems.

Working Principle

When the valve shaft rotates, the valve disc will move up and down with the rotation of the shaft, thereby changing the gap between the valve disc and the valve seat. When the gap between the valve disc and the valve seat increases, the flow and pressure of the fluid will also increase; when the gap between the valve disc and the valve seat decreases, the flow and pressure of the fluid will also decrease

PVC Butterfly Valve has the advantages of simple structure, convenient operation, and good sealing performance. It is widely used in water supply and drainage, fire protection, air conditioning and other fields.

Product Features

1. It is convenient and quick to open and close, labor-saving, and has low fluid resistance, and can be operated frequently.

2. Simple structure, small size, short structure length, small volume, light weight, suitable for large-diameter valves.

3. It can transport mud and accumulate the least liquid at the pipe mouth.

4. Under low pressure, good sealing can be achieved.

5. Good adjustment performance.

6. When fully open, the effective flow area of ​​the valve seat channel is large and the fluid resistance is small.

7. The opening and closing torque is small. Since the butterfly plates on both sides of the shaft are basically equally affected by the medium, and the torque is generated in the opposite direction, it is easier to open and close.

8. The sealing surface material is generally made of rubber and plastic, so the low-pressure sealing performance is good.

9. Easy to install and simple to operate.

Selection conditions

Working conditions: It is necessary to understand the working conditions of the PVC Butterfly Valve, including the medium, temperature, pressure, etc., to ensure that the selection of the PVC butterfly valve meets these conditions.

Valve size: According to the pipeline size and flow requirements, select the appropriate PVC butterfly valve size to ensure smooth fluid flow.
