The Grooved Gate Valve is engineered for fast installation and reliable flow control in commercial and industrial fire protection systems. Featuring standard grooved ends compatible with roll-grooved steel pipes, it reduces installation labor compared to flanged alternatives while maintaining a bubble-tight seal.
Available Configurations: Non-Rising Stem (NRS) for underground or confined spaces; Outside Screw and Yoke (OS&Y) for immediate open/closed visual verification.
Standard Ratings: UL Listed and FM Approved for 300 PSI (2.07 MPa) working pressure.
Size Range: 2 inches through 12 inches (DN50 to DN300).

Key Features & Manufacturing Integrity
Ductile Iron Body & Wedge: Cast from ASTM A536 Grade 65-45-12 ductile iron, providing high tensile strength and impact resistance exceeding standard gray cast iron.
Encapsulated Wedge: The ductile iron wedge is fully encapsulated with high-grade EPDM rubber, ensuring resilient seating, corrosion resistance, and bubble-tight shutoff at rated pressure.
Stem Assembly: Rolled-thread stainless steel stems (AISI 304/420) offer high operating torque resistance and smooth operation over thousands of cycles.
Internal Manufacturing & Quality Control:
Bodies are produced via automated resin-sand molding lines to ensure uniform wall thickness and defect-free castings.
100% shell and seat hydrostatic pressure testing performed prior to factory dispatch, complying with UL/FM test protocols.
Applications
Commercial building fire sprinkler distribution lines.
High-rise fire standpipe and riser manifolds.
Fire pump suction and discharge isolation loops.
Industrial facility deluge and pre-action system control headers.
OEM & Customization Support
Private Labeling: Cast-in or laser-etched customer logos, part numbers, and specific tag requirements on valve bodies.
Dimensional Adaptation: Custom grooved end dimensions or face-to-face lengths matching legacy system replacements.
Accessory Integration: Pre-drilled and tapped mounting pads for supervisory tamper switches and monitoring gear boxes.
Testing, Quality & Documentation
Certifications: UL Listed and FM Approved documentation provided with every batch.
Traceability: Heat codes stamped directly onto valve bodies for raw material traceability.
Test Reports Supplied:
Material Test Reports (MTR) per EN 10204 3.1.
Factory hydrostatic shell and seat pressure test certificates.
Coating thickness and adhesion test logs.
FAQ
Q: Are these valves compatible with standard roll-grooved carbon steel pipes?
A: Yes. The groove dimensions strictly conform to AWWA C606 specifications for standard steel pipe couplings.
Q: Do you supply UL/FM official certificate copies for engineering submittals?
A: Yes. Complete UL/FM certificate numbers, installation manuals, and CAD/BIM drawing files are provided upon inquiry.
Q: What is the minimum order quantity (MOQ) for custom-branded valves?
A: MOQ depends on size specifications; typically starts at 50 units per size for custom casting or private labeling.
Q: What is the standard lead time for bulk orders?
A: Standard stock items ship within 15 to 25 days. Production lead time for custom container loads is 35 to 45 days.
