What is the function of a bypass valve?

A bypass valve is a valve used to divert fluid flow around a section of pipe or another component. This allows for maintenance, repair, or pressure balancing without shutting down the entire system. Bypass valves can be used in both liquid and gas systems, and come in a variety of types and sizes.

The most common type of bypass valve is a globe valve, which has a circular body with a disk that moves vertically to open or close the flow. Globe valves are used in low to medium-pressure systems, and are typically made of brass, stainless steel, or iron.

Gate valves are another type of bypass valve, and they use a wedge-shaped gate to block the flow. Gate valves are used in high-pressure systems, and are typically made of cast iron or steel.

Butterfly valves are a type of bypass valve that use a rotating disk to control the flow. Butterfly valves are used in low-pressure systems, and are typically made of plastic, aluminum, or stainless steel.

Check valves are a special type of bypass valve that allows fluid to flow in one direction only. Check valves are used to prevent backflow in the system, and are typically made of brass, stainless steel, or iron.

Bypass valves are an essential component of many industrial, commercial, and residential systems, and they provide a convenient way to control the flow of fluids without shutting down the entire system.
