Spark DN150 Fire-Specific Flanged OS&Y Resilient Seated Gate Valve
Spark DN150 Fire-Specific Flanged OS&Y Resilient Seated Gate Valve
This is Spark’s DN150 fire-specific flanged outside screw & yoke (OS&Y) resilient seated gate valve, a core on-off control component for various fire protection piping networks (wet, pre-action, and deluge systems). It is widely utilized in high-rise buildings, commercial complexes, industrial plants, and municipal fire protection projects. The OS&Y design allows for intuitive determination of the valve’s open/closed status through the movement of the stem, ensuring precision during fire emergency operations. The resilient seated structure achieves zero-leakage sealing, effectively preventing the waste of fire water resources. The body is constructed from QT450 ductile iron with an anti-corrosion coating, offering both exceptional structural strength and corrosion resistance. It is a critical piece of equipment that ensures the reliable and efficient operation of fire protection system pathways.

Frequently Asked Question
FAQ
What is a pressure relief valve?
+
-
The Forede pressure relief valve (PRV) is a mechanical device that releases gas or liquid from a system when the pressure exceeds a predetermined limit. PRVs are used to prevent over-pressurization, which can damage machinery or people
What is the purpose of pressure relief valve?
+
-
The PRV Pressure relief valve is a safety device that prevents a system from becoming dangerously pressurized by automatically releasing excess pressure. PRVs are used in many industrial settings, including power plants, chemical plants, and refineries, as well as in boilers, tanks, and pipelines.
How should i install the pressure relief valve?
+
-
The pressure relief valve came with flange end connection, please inform us the flange standard you need before placing the order to ensure the PRV valve could compatible with exist system.
What is the shipping methods?
+
-
It could be shipped by sea,by air or by express(EMS,UPS,DHL,TNT,FEDEX and ect). Please confirm with us before placing orders.
How can i get price?
-
We usually quote within 24 hours after we get your inquiry(Except weekend and holidays).If you are very urgent to get the price, please email us or contact us in other ways so that we can offer you a quote.

Spark DN150 Fire-Specific Gate Valve Launches, Building a Zero-Leakage Safety Line for High-Flow Piping Networks
Spark, a global leader in fluid control solutions, today announced the launch of its new flagship product, the DN150 Fire-Specific Flanged OS&Y Resilient Seated Gate Valve. Engineered to meet the increasingly stringent reliability and efficiency demands of fire protection systems in modern large-scale buildings and industrial facilities, this product aims to provide a safe, precise, and efficient on-off control solution for high-flow fire protection piping networks.
The core advantages of the Spark DN150 Fire Gate Valve lie in its exceptional sealing performance and intuitive operational design. Utilizing a high-quality resilient rubber seat, the valve achieves drip-tight, zero-leakage sealing in any open or closed position, completely resolving the common internal leakage issue found in traditional gate valves. This ensures that the fire protection system can maintain maximum water pressure and flow when it matters most. Its distinctive OS&Y design provides clear visibility of the valve’s operational status, significantly enhancing the efficiency and accuracy of fire inspections and emergency operations, and saving valuable response time for firefighters.
To ensure long-term stable operation in harsh environments, the valve body is constructed from high-grade QT450 ductile iron with a professional anti-corrosion treatment, endowing the product with superior impact resistance, wear resistance, and corrosion resistance. The standard flanged connection ensures seamless integration and quick installation with existing fire protection piping systems.
As a fire-specific product certified by CCCF and other international authoritative bodies, the Spark DN150 Gate Valve not only complies with national fire safety regulations but also represents the industry’s leading safety standards. Its launch provides a robust and reliable guarantee for the fire safety of critical infrastructure such as high-rise buildings, data centers, and large shopping malls, further demonstrating Spark’s commitment to "protecting life and property." The product is now available for order. For more information, please visit the official Spark website.
