It is UL Listed (EX16012) and FM Approved, ensuring global compliance for critical safety infrastructure. Manufactured in the UAE and distributed internationally, this valve is ideal for use in fire pump rooms, commercial fire sprinkler networks, and industrial fire suppression systems.

⚙️ Design & Construction – Built for Strength and Efficiency

This valve features grooved-end connections that meet ANSI/AWWA C606 standards, allowing quick and secure installation. The top flange interface, compliant with ISO 5211, ensures easy integration with gear operators, tamper switches, or remote supervision devices.

Its supervised capability lets facility managers monitor the valve’s status (open or closed), adding an extra layer of control to fire systems where timely response is critical. The valve is rated for 300 PSI working pressure and 600 PSI hydrostatic test pressure, making it suitable for high-pressure applications.

To withstand various operating environments, the valve is rated for temperatures up to 80°C (176°F). This makes it suitable for both indoor and outdoor installations in different climatic zones.
