Gate Valves
What are Gate Valves?
Gate Valves are linear motion valves used to start or stop the flow of liquids in a pipeline. These valves operate by lifting a gate out of the flow path, allowing full unobstructed passage. Ideal for applications requiring minimal pressure drop and bi-directional flow, gate valves are widely used in water supply systems, oil and gas processing, and industrial piping networks.
Asiad Steel Industries is a leading manufacturer and exporter of high-quality Gate Valves for standard and customized applications across various sectors.

Do you have questions?
When should gate valves be used over globe valves?
Gate valves are best for on/off control where flow regulation is not required. They provide full flow or complete shut-off.
Do gate valves work for throttling applications?
Not ideal. Gate valves are not recommended for throttling as partial opening may damage the sealing surfaces.
What is the difference between rising and non-rising stem types?
Rising stem valves indicate valve position externally, while non-rising stem valves are better for space-constrained setups.
Are gate valves suitable for slurries or viscous media?
Not typically. Viscous or slurry media may lead to accumulation and damage. Specialized valves are recommended.
