Product Introduction

The NRS (Non-Rising Stem) flanged gate valve features a non-rising stem design that requires less vertical clearance than an OS&Y valve, making it ideal for confined spaces. A visual indicator disc shows open/closed status. Suitable for fire protection and water supply systems.

Features

✓Non-rising stem — compact vertical footprint
✓Visual open/closed indicator disc
✓Flanged end connections
✓Ductile iron body — ASTM A536
✓UL Listed / FM Approved
