Description

Technical Specifications (Material Focus):
The 14" Wafer Check Valve by Nibco Inc. is engineered for fire protection system applications requiring compact and reliable backflow prevention. The valve’s wafer-style design enables installation between ANSI B16.5 flanges without additional pipe length, optimizing space in congested fire protection piping configurations. The body is constructed from ASTM A126 Grade B cast iron, offering corrosion resistance suitable for wet fire sprinkler environments. Internal components include stainless steel springs and 300-series stainless steel shafts resistant to rust and fatigue under fluctuating flow conditions. The valve disc features a precision-machined stainless steel plate paired with a resilient, replaceable EPDM seal, ensuring tight shutoff to prevent reverse flow contamination.

Regulatory Compliance:
This wafer check valve is UL Listed under UL 213 for check valves used in fire protection systems, confirming its fitness for life-safety applications. Additionally, it holds FM Approval specifically for fire service backflow prevention devices. The valve meets ASSE 1012 standards, ensuring compliance with recognized backflow prevention performance requirements. It supports adherence to NFPA 13 (Standard for the Installation of Sprinkler Systems) through its design features that enable unobtrusive integration into fire mains and distribution lines.

Operational Compatibility:
Rated for a maximum working pressure of 175 PSI (12.1 bar), the valve is suitable for typical fire protection system operating ranges. It maintains reliable function within a temperature scope of 33°F to 180°F (0.5°C to 82°C), accommodating both ambient and elevated water temperatures in fire sprinkler networks. Connection compatibility includes wafer-style between standard ANSI B16.5 Class 125 or Class 150 flanges, allowing straightforward retrofit or new installations. Flow orientation is unidirectional with clear upstream/downstream markings and is designed for installation in horizontal or vertical pipe runs with upward flow, providing flexibility for complex plumbing layouts.

Use Cases and Industry Suitability:
Ideal for commercial and industrial fire protection systems, this 14" wafer check valve excels in applications requiring reliable backflow prevention where space constraints limit the use of traditional swing or in-line check valves. Its thin-wafer profile is particularly advantageous in retrofit projects, multi-story buildings, and places where minimizing pressure loss is critical. Fire protection contractors and plumbing engineers benefit from its balance of robust material construction and ease of installation, reducing labor time and maintenance disruptions. The valve’s EPDM seat maintains performance under the intermittent flow scenarios typical in sprinkler activation, preventing system contamination and ensuring readiness in emergencies.

Value-Added Features:
This wafer check valve’s corrosion-resistant cast iron body paired with stainless internal components prolongs service life in corrosive wet fire sprinkler environments. Its user-friendly design simplifies alignment and flange bolt-up, reducing installation errors and downtime. Unlike globe style or larger swing check valves, the wafer design offers minimal flow resistance, preserving system hydraulics and optimizing pump and water supply efficiency. Quick access to internal components enables straightforward maintenance and inspection, critical for compliance with NFPA 25 inspection protocols and local fire codes.
