Product Q&A

Q:1. What is a gate valve used for?

A gate valve is mainly used to open or close the flow in a pipeline system. It is widely used in fire protection, water supply, HVAC, irrigation, and industrial piping systems.

Q:2. Can a gate valve be used for flow control?

Gate valves are mainly designed for full open or full close service. They are not recommended for long-term throttling or flow regulation, because partial opening may damage the wedge and sealing surface.

Q:3. What is a resilient seated gate valve?

A resilient seated gate valve uses an EPDM or NBR rubber-covered wedge to provide tight sealing. It is commonly used for water supply, fire protection, HVAC, and irrigation pipeline systems.

Q:4. Do you supply FM/UL approved gate valves?

Yes. We can supply FM/UL approved gate valves for fire protection systems. Available options include NRS gate valve, OS&Y gate valve, flanged gate valve, grooved gate valve, and other project-required types.

Q:5. What is the difference between NRS and OS&Y gate valves?

NRS means non-rising stem. The stem does not move up and down during operation, so it is suitable for limited-space installation. OS&Y means outside screw and yoke. The stem rises when the valve opens, making the open/close position easy to see. It is commonly used in fire protection systems.
