Why Buy From Us
Every quote personally reviewed. Direct sourcing from top manufacturers.
The stainless‑steel union with an integrated timer delivers a secure, corrosion‑resistant connection for boiler and hydronic loop applications, allowing precise flow control. The 110223B-244 Armstrong Astro 220SSU‑T model is engineered for quick installation and long‑term durability.
When the timer reaches the programmed interval, the internal valve closes automatically, halting flow without manual intervention. This mechanical timing action reduces pump run‑time, saves energy, and protects downstream equipment from over‑pressurization.
Key System Performance Baselines:
- Leak‑Free Seal: Guarantees a tight joint up to 150 psi operating pressure.
- Timer Accuracy: Provides ±5 seconds timing precision for scheduled flow shutdowns.
- Corrosion Resistance: Stainless‑steel construction exceeds ASTM A240 standards for longevity.
- Temperature Range: Operates reliably from -20 °F to 250 °F, covering most heating systems.
🚨Application Profile: Ideal for boiler feed lines, chilled water circuits, radiant heating loops, and any hydronic system requiring timed flow control.
