Armstrong 516837-302 - Flo-Trex FSA Combination Valve, 2", Straight Angle Pattern

Optimizing discharge efficiency, the Armstrong Flo-Trex valve is designed to safeguard pumping equipment from reverse flow and pressure surges. This versatile component, identified as model 516837-302, integrates multiple system requirements into a compact, durable assembly that simplifies piping installations.

By serving as a shut-off valve, non-slam check valve, and throttling device, this 2" unit eliminates the need for individual components. Its configuration acts as a 90° elbow, effectively reducing fittings, minimizing pressure drop, and ensuring reliable pump performance across diverse hydronic applications.

Key System Performance Baselines:

• Multi-function integration: Combines shut-off, check, and throttling capabilities in one device.
• Non-slam operation: Reduces noise and vibration, preventing damaging hydraulic shock.
• Flow control: Allows for precise system balancing via integral throttling features.
• Simplified piping: Replaces standard 90° elbows to minimize total system resistance.

⚠️ Application Profile: Ideal for commercial hydronic heating and cooling systems, chilled water loops, and boiler feed discharge lines where reliable pump isolation and flow management are required.
