UL Grooved End Resilient Seated NRS Gate Valve

This is a UL/FM-certified grooved end resilient seated non-rising stem (NRS) gate valve—a high-performance fluid control component engineered for fire protection, water supply, and industrial systems.
Designed with grooved connections, it enables fast, tool-free installation (no welding/threading required), cutting on-site labor time significantly. The resilient EPDM rubber seat ensures bubble-tight sealing (zero leakage) even under pressure, while the non-rising stem (NRS) design keeps the stem internal during operation—perfect for compact spaces like wall-mounted pipe racks or shipboard pipelines.
Constructed from ductile iron (high strength & corrosion resistance) with a bright red epoxy coating (fire safety-compliant), it meets global standards (UL 262, FM 1120/1130) for reliability in critical applications. The large ergonomic handwheel allows smooth, low-effort operation, even in emergency scenarios.
Whether for building fire sprinklers, municipal water networks, or industrial fluid lines—this valve delivers speed, safety, and durability in one solution.

Product Formation

This is a UL-listed grooved end resilient seated non-rising stem (NRS) gate valve, designed for fire protection, water supply, and industrial fluid systems. It features a grooved connection (compatible with grooved pipe fittings) for quick, tool-free installation, and a resilient (rubber) seat that ensures bubble-tight sealing. The NRS design means the stem does not extend outward when opening/closing, saving space—ideal for compact installations. Finished in bright red (standard for fire safety), it meets UL/FM safety standards, making it suitable for critical applications like building fire sprinkler systems.

Product Features

UL/FM Certified: Complies with global fire safety standards, ensuring reliability in life-safety systems.
Grooved End Connection: Enables fast, leak-proof assembly without welding or threading (reduces installation time by 50%+).
Resilient Seating: Rubber seat provides zero-leak performance and long service life (resists wear from water/fluid flow).
Non-Rising Stem (NRS): Stem remains internal when operating, perfect for tight spaces (e.g., wall-mounted pipe racks).
Durable Construction: Ductile iron body (high strength, corrosion resistance) + epoxy powder coating (red) for harsh environments.
Easy Operation: Large handwheel with ergonomic grip for smooth, low-effort opening/closing (even under pressure).

Application Scenarios

Fire Protection Systems:

Building fire sprinkler networks (commercial/residential high-rises, malls, hospitals) — UL/FM certification ensures compliance with fire safety codes.
Industrial fire suppression systems (factories, chemical plants, warehouses) — reliable sealing prevents water leakage in critical emergency setups.

Water Supply & Distribution:

Municipal water pipelines (underground/indoor) — grooved connections simplify maintenance and repair in tight spaces.
Building water supply systems (hot/cold water lines) — resilient seat resists corrosion from water and ensures long-term leak-free performance.

Industrial Fluid Systems:

Low-pressure industrial fluid transport (cooling water, process water) — ductile iron body withstands moderate mechanical impact in workshop environments.
Marine & offshore auxiliary systems (shipboard water pipelines) — compact NRS design fits confined ship spaces.
