The Main Control Valve for Your Fire Protection System
Every fire protection system—be it a sprinkler, hydrant, or other type—requires a main control valve that is reliable, robust, and easy to verify its status. AFCOVALVES meets this need with the GV01 Series OS&Y Gate Valve, a valve specifically engineered for the most demanding fire protection applications.
With its robust construction and international certifications, the GV01 is the trusted choice to serve as the primary gateway for your safety system.
The OS&Y Design: A Crucial Visual Safety Indicator
One of the most important features of the GV01 is its OS&Y (Outside Screw and Yoke) design.
- How It Works: When the handwheel is turned to open the valve, the threaded stem rises out of the valve body. Conversely, the stem lowers when the valve is closed.
- Why It Matters: This rising stem provides a clear, unmistakable visual indication that the valve is in the open position. In an emergency, firefighters or inspectors can quickly see from a distance that the system is active and not accidentally shut off. This is why the OS&Y design is a mandatory requirement in many fire protection standards.
Robust Construction for Long-Term Reliability
AFCOVALVES engineered the GV01 Series with high-quality materials to ensure long-lasting performance:
- Ductile Iron Body: Provides superior strength to handle high pressures.
- Fusion Bonded Epoxy Coating: Coats the interior and exterior of the valve, offering maximum protection against corrosion.
- Resilient Seated Wedge: The EPDM rubber-encapsulated wedge creates a bubble-tight shut-off, preventing any leakage.
- Stainless Steel Stem: Resists rust and corrosion for smooth operation for years to come.
UL/FM Certification: A Guarantee of Quality and Compliance
Reliability is non-negotiable in a life-safety system. The GV01 Series is rigorously tested and is UL Listed and FM Approved. This is proof that the valve has met the highest standards for performance, strength, and durability set by the world’s most respected safety organizations.
Connection Flexibility
For easy integration into various system designs, the GV01 is available in multiple end-connection types:
- Flanged x Flanged
- Grooved x Grooved
- Flanged x Grooved Combination
In conclusion, the AFCOVALVES GV01 Series OS&Y Gate Valve is more than just a valve. It is a critical safety component that provides the control, reliability, and visual verification required by every modern fire protection system.
