Valve Comparison
Ball valve vs. gate valve: compare the duty, operating method and installation.
Ball valves
A rotating ball provides quarter-turn operation. Seat and trim selection matter for shut-off performance, media compatibility and temperature suitability. Standard isolation designs should not be assumed suitable for continuous throttling.
Gate valves
A gate moves into or out of the flow path. These valves are generally used for isolation and need adequate installation clearance for the stem and operator.
Which one fits your project?
Compare the required duty, size, differential pressure, frequency of operation, maintenance plan and the project piping specification. Ask for a configuration-specific proposal rather than choosing by valve family alone.
