Manual Ductile iron Cast iron rubber disc gate valve for PVC pipe

Rubber disc gate valves are designed to control the flow of fluids in PVC (Polyvinyl Chloride) piping systems. These valves are particularly useful in applications where the fluid medium is compatible with rubber materials and where the operating conditions are within the design limits of the valve. The rubber-disc gate valve is known for its durability, ease of operation, and tight shut-off capabilities.

Design and Construction

The rubber disc gate valve typically features a rubber disc or plug that is used to control the flow of fluid through the valve. The rubber element is designed to seal against the valve body when the valve is closed, ensuring a tight shut-off and preventing leakage. The rubber disc is usually made from materials such as EPDM (Ethylene Propylene Diene Monomer) rubber, which is resistant to a wide range of chemicals and suitable for use with potable water.

Features of Rubber Disc Gate Valves for PVC Pipes

• Compatibility: The rubber disc is chosen based on the type of fluid that will be passing through the valve to ensure compatibility and prevent degradation of the rubber material.
• Tight Shut-Off: The rubber disc provides a good seal, ensuring that the valve can effectively stop the flow of fluid when necessary.
• Corrosion Resistance: The use of rubber and PVC materials in the valve construction makes it resistant to corrosion, which is particularly beneficial in harsh environments or when dealing with corrosive fluids.
• Ease of Operation: These valves are designed for easy manual operation, often with a handwheel or lever mechanism that allows for quick and precise control of the flow.
