FAQ
Why should I choose an NRS gate valve over an OS&Y model?
If you are burying the valve or installing it under a low ceiling, you need an NRS valve. Since the stem doesn't rise, you don't need to worry about the valve hitting a ceiling or needing a deep, expensive vault for underground access.
Does the flat-bottom design really prevent leaks?
Yes. Traditional gate valves have a "pocket" at the bottom where stones and silt collect, preventing the gate from closing fully. Our resilient seat design eliminates this pocket, so the wedge seals against a flat surface, and debris is simply washed away by the flow.
What kind of maintenance does this valve require?
Very little. Thanks to the FBE coating and the EPDM-wrapped wedge, the internal parts are shielded from the water. Regular cycling of the valve is usually all that's needed to keep the stem moving smoothly for years.
