Technical Specifications (Material Focus)
The 2000SSLG Backflow Preventer Valve Less Gate Valves feature a main body constructed from ASTM A536 ductile iron, recognized for its enhanced tensile strength and resistance to impact. This high-strength material is finished with corrosion-resistant coatings suitable for harsh commercial and industrial environments. Internal components incorporate 300-series stainless steel springs and fasteners, ensuring mechanical durability and resilience against corrosion over extensive operational cycles. The valve less gate valves integrated with this assembly omit traditional valve stems, reducing potential leak points and maintenance complexities while maintaining robust flow control.
Regulatory Compliance
This assembly is UL Listed in accordance with UL 312 standards for backflow prevention devices, confirming rigorous testing for safety and reliability. Additionally, it holds FM Approval, meeting Factory Mutual's stringent criteria for fire protection water supply equipment. The 2000SSLG complies with NFPA 13 and NFPA 25, governing installation, inspection, testing, and maintenance of fire sprinkler systems and backflow prevention, respectively. This compliance ensures the product supports national fire protection codes and potable water safety standards.
Operational Compatibility
Engineered for seamless integration with existing fire protection and potable water infrastructure, this backflow preventer is compatible with standard ductile iron piping systems. It accommodates valve less gating configurations, eliminating the need for separate valve stems, which enhances flow reliability and reduces maintenance failure points. The unit is rated for a maximum working pressure of 175 PSI (12.1 bar), supporting high-pressure fire service lines without compromising integrity. Connection options include flanged ends compliant with ANSI B16.1 and grooved ends meeting AWWA C606 standards, providing flexibility for varied installation preferences and piping layouts.
The 2000SSLG excels in applications requiring contamination prevention of potable water supplies in commercial buildings, fire protection systems, and irrigation networks. Its valve less gate valve design minimizes wear and simplifies system maintenance, thereby reducing downtime and lifecycle costs. This product is specifically suited for engineers and facility managers seeking a reliable, code-compliant backflow prevention solution that supports NFPA mandates and robust operational demands.
Installation options include both horizontal and vertical orientations, facilitating versatile placement within mechanical rooms or underground vaults. Pre-drilled test cocks enable straightforward differential pressure testing, aligning with annual inspection protocols. This supports ongoing verification of device performance and regulatory compliance without necessitating system shutdowns or extensive disassembly.
In environments where system reliability and potable water protection are critical, the 2000SSLG's durable materials and valve less gating mechanism provide a distinct advantage. By focusing on corrosion resistance, mechanical simplicity, and adherence to fire protection standards, it offers professionals an effective tool to mitigate backflow risks and maintain water system integrity under demanding operational conditions.
