PVC Butterfly Valve

PVC Butterfly Valve is a valve made of polyvinyl chloride (PVC) material, which has the characteristics of light weight, corrosion resistance, easy installation and maintenance.

Puhui Industry can supply various sizes of 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.

PVC Butterfly Valve Working Principle

The working principle of the PVC Butterfly Valve is based on the switch of the valve core, and the opening and closing of the valve core are used to control the on and off of the fluid. This valve consists of a valve body, a valve cover, a valve stem, and a valve core, in which the valve core is connected to the valve cover through the valve stem and is also connected to the valve body. When the valve core is in the closed position, a closed channel is formed between the outlet and the inlet of the valve body, preventing the fluid from passing through. When the PVC valve needs to be opened, the valve core moves along the direction of the valve stem so that the valve core hole is aligned with the inlet and outlet of the valve body, so that the fluid can pass through the valve body and the valve is opened. The valve core continues to move along the direction of the valve stem, so that its hole is out of alignment with the flow channel of the valve body, thereby closing the valve again. ‌

PVC butterfly valves are highly corrosion-resistant and lightweight and are widely used in many industries such as the chemical industry, water treatment, agriculture, and construction due to their high corrosion resistance, excellent sealing, and low cost. ‌

Advantages

1. Strong corrosion resistance: PVC material has good corrosion resistance and can resist the erosion of various chemical media, especially suitable for handling corrosive fluids. ‌

2. Light weight: Compared with metal butterfly valves, PVC Butterfly Valves is lighter and easier to install and transport. ‌

3. Easy to install and maintain: The structure of the PVC Butterfly Valve is relatively simple, and the installation and maintenance process is relatively easy. ‌At the same time, its sealing performance is good, reducing the risk of leakage. ‌

1. Affordable price: Its relatively low cost makes it an affordable choice in many applications.
