Hydronic Closely Spaced Tee | 8000S Series | Solder × Solder w/ Isolation Valve
Red-White Valve’s 8000S Hydronic Closely Spaced Tee combines hydraulic separation and isolation functionality in a single, compact fitting. Designed for high-performance primary/secondary loop systems, it uses a full-port chrome-plated brass ball valve between two precision-spaced tees to prevent crossflow and maintain hydraulic balance. Built from DZR lead-free brass and rated for 600 PSI WOG, it delivers unmatched performance for commercial and industrial hydronic systems.
Key Features & Benefits
- Dual Function Design — Combines hydraulic separation and isolation valve into one compact assembly, reducing installation points by up to 40%.
- High-Pressure Rated — 600 PSI WOG rating handles extreme pressures in industrial and commercial systems.
- DZR Lead-Free Brass Body — ASTM B30 C87850 construction provides dezincification resistance and compliance with NSF/ANSI 61 & 372.
- Full-Port Chrome-Plated Ball — Maximizes flow and minimizes pressure loss; blow-out-proof stem for safety and longevity.
- Solder End Connections — ASME B16.18 compliant solder joints ensure permanent, vibration-resistant sealing.
- PTFE & EPDM Sealing Components — Virgin PTFE seats and EPDM O-rings provide smooth operation across wide temperature ranges.
- Temperature Range — Operates from 15°F to 260°F (with approved antifreeze/anti-boil fluids).
