Bypass Valves: Function, Types, and Applications

A bypass valve diverts fluid flow around a pipe section or component, allowing maintenance, repair, or pressure balancing without system shutdown. Used in liquid/gas systems; various types/sizes.

Common Types

• Globe Valve: Circular body, vertical disk; low/medium pressure; brass, stainless steel, iron.
• Gate Valve: Wedge-shaped gate; high pressure; cast iron, steel.
• Butterfly Valve: Rotating disk; low pressure; plastic, aluminum, stainless steel.
• Check Valve: Allows one-way flow only; prevents backflow; brass, stainless steel, iron.

Bypass valves are essential in industrial, commercial, and residential systems for convenient flow control without full shutdown.
