Product Q&A

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

A grooved NRS gate valve is mainly used for fire protection, water supply, HVAC, and industrial pipeline systems. The grooved end connection allows fast installation with grooved couplings.

Q:2. What does NRS mean?

NRS means Non-Rising Stem. The stem does not move up and down during operation, making the valve suitable for compact installation and limited-space pipeline systems.

Q:3. Is this valve FM approved and UL listed?

Yes. FM approved and UL listed options are available for fire protection projects.

Q:4. What standard is the grooved end designed according to?

The grooved end is designed according to AWWA C606.

Q:5. What is the working pressure of this valve?

The working pressure is PN25 / 362 PSI.
