FAQ

What is a double disc check valve?

A double disc check valve is a device that allows fluid to flow in one direction while preventing backflow, using two discs to create a tight seal.

How does a double disc check valve work?

The valve opens when fluid flows in the forward direction, allowing it to pass through. If there is a reverse flow, the discs close to prevent backflow.

What materials are used in the construction of double disc check valves?

They are commonly constructed from stainless steel, cast iron, and bronze, providing durability and resistance to corrosion.

What sizes are available for double disc check valves?

Double disc check valves come in a wide range of sizes, typically from 2 inches to 24 inches, to accommodate various piping requirements.

Are double disc check valves suitable for high-pressure applications?

Yes, double disc check valves are designed to withstand high-pressure conditions, with ratings available up to ANSI 300.
