Description

Technical Specifications (Material Focus)

Main Body: Manufactured from ASTM A536 ductile iron, engineered for high mechanical strength and impact resistance in fire protection applications.
Internal Components: Precision-engineered 300-series stainless steel stems, nuts, and fasteners deliver exceptional corrosion resistance and mechanical durability within the valve assembly.
Valve Design: Outside Stem & Yoke (OS&Y) configuration enables visible position indication and facilitates reliable manual operation and inspection.
Check Valves: Dual check modules designed to prevent reverse flow of contaminated water, constructed for low pressure loss and long service life.

Regulatory Compliance

UL Listed: Certified to UL 312 for Reduced Pressure Principle Backflow Preventers, ensuring suitability for potable water protection in fire systems.
FM Approved: Approved by Factory Mutual to meet rigorous performance standards for fire protection reliability.
NFPA Standards: Complies with NFPA 13, NFPA 24, and NFPA 25, enabling seamless integration with national fire sprinkler and water supply system codes.

Operational Compatibility

Size & Connections: 3-inch nominal size, compatible with standard NRS (Non-Restricting Service) flanged or grooved connections common in fire protection piping.
Pressure Rating: Capable of withstanding system pressures typical of fire protection networks, supporting high-flow demand without compromising backflow prevention.
Installation Environment: Suitable for underground or mechanical room applications, designed to resist environmental factors and facilitate routine maintenance.

The 3" 4000SS OS&Y Reduced Pressure (RP) Backflow Preventer is engineered specifically to safeguard potable water supplies from contamination risks posed by backflow in fire protection systems. Its construction from ductile iron and stainless steel components addresses the dual challenges of mechanical stress and corrosion commonly encountered in commercial, industrial, and municipal fire sprinkler installations.

This device’s OS&Y design offers visible stem position and accessible operation, simplifying inspection and aligning with strict maintenance protocols mandated by fire codes. By incorporating this backflow preventer, system designers and facility managers ensure uninterrupted fire suppression system performance while maintaining compliance with critical safety standards such as UL 312, FM Approval, and pertinent NFPA codes.

Designed for integration with underground piping and fire pump supply lines, this assembly reliably blocks potential cross-connections that could compromise water quality. The rugged material selection and precision engineering allow for dependable long-term service even in harsh conditions. Its compatibility with standard 3-inch piping and common connection types facilitates straightforward retrofit or new installations without extensive modifications.

In scenarios where maintaining potable water purity is paramount—such as hospitals, manufacturing plants, municipal water systems, and commercial complexes—the 3" 4000SS OS&Y RP Backflow Preventer provides a robust, code-compliant solution. Its balance of strength, corrosion resistance, and ease of maintenance supports both operational reliability and regulatory adherence essential in fire protection infrastructure.
