What is a Ball Valve? What are the Functions of Ball Valves?
A ball valve is a quarter-turn valve that uses a hollow, perforated ball to control flow. Rotating the ball 90° quickly opens or closes the valve.
Functions of Ball Valves
Quick Opening & Closing Only a 90° turn is needed for full open or close, making operation very fast.
Excellent Sealing Performance Ball valves provide tight, nearly zero-leakage sealing, ideal for gas, LNG, chemical, and oil systems.
Wide Media Compatibility Suitable for liquids, gases, steam, corrosive chemicals, oil, and high-pressure media.
Bi-directional Flow No inlet or outlet direction limitation during installation.
Long Service Life & Durability Resistant to wear, corrosion, and frequent operation.
Compact Structure & Easy Maintenance Widely used in industrial pipelines, HVAC, oil & gas, chemical, water treatment, and mechanical systems.

What is a Gate Valve? What are the Functions of a Gate Valve?
A gate valve is a type of linear motion valve used to fully open or fully close fluid flow in a pipeline. It uses a movable gate or wedge-shaped disc that lifts up or lowers down to control flow. It is not designed for flow regulation, only for on‑off service.
Functions of a Gate Valve
On-off control of fluid flow It is mainly used to completely start or stop the flow of liquid, gas, steam, or oil in pipelines.
Low pressure drop When fully open, it provides a straight, unobstructed passage, allowing fluid to pass with very little resistance.
Bi-directional flow capability It allows flow in both directions, so there is no strict inlet or outlet direction during installation.
Good sealing performance It provides reliable tight shut-off, making it suitable for water systems, oil pipelines, steam systems, and industrial pipelines.
Suitable for large-size and high-temperature applications Gate valves are widely used in water supply, petrochemical, power plants, oil and gas transmission, and other heavy industrial fields.
