Viking Clapper Assembly for Fire Protection Valves

The Viking Clapper Assembly is a vital flow control component engineered for fire protection infrastructure, including dry pipe valve and swing check valve systems. It installs directly within the valve body to maintain system integrity, manage directional water flow, and prevent reverse flow contamination or costly system failures during emergencies.

This assembly satisfies stringent code compliance requirements under NFPA 13 for fire sprinkler installations. It meets rigorous national and international life safety standards, ensuring full regulatory compliance for commercial and industrial facility maintenance.

Key Features & Construction

• Durable Construction: Crafted from high-strength ASTM A536 ductile iron to provide robust mechanical strength and corrosion resistance against harsh environments.
• Corrosion-Resistant Hardware: Internal hinges, pins, and fasteners utilize stainless steel to withstand continuous water exposure and fluctuating pressure.
• Precision Engineering: Designed for consistent sealing and optimal water flow management that minimizes pressure loss and reduces water hammer effects.
• Operational Capacity: Supports maximum working pressures up to 175 PSI (12.1 bar).
• Flexible Integration: Supports both horizontal and vertical installation positions to streamline retrofits and minimize system downtime.
