Gate valves are linear-motion isolation valves offering a full, unobstructed bore when fully open, making them suitable for low-pressure-drop on/off service. They are not intended for throttling. Key selection factors are body/bonnet construction, stem type (rising vs. non-rising), wedge design, and pressure class per the applicable API/ASME standard.
Q: What is a gate valve used for?
A: Gate valves are used for fully open or fully closed isolation where minimal flow restriction is desired. They are not recommended for continuous throttling.
Q: Which standards govern gate valves?
A: Common standards include API 600 (bolted bonnet steel), API 602 (compact steel), API 603 (corrosion-resistant), and API 6D for pipeline service.
Guidance reflects general engineering practice for gate valves; confirm against the project specification and applicable standards before procurement.
