The Check‑Trol isolation flange delivers secure shut‑off and back‑flow prevention for hydronic heating and cooling loops. Designed for the **101233LF** model, this flange provides a compact, field‑replaceable solution that isolates the check valve without compromising system integrity.
It combines a spring‑loaded check valve with an isolating swivel, allowing technicians to disengage flow for servicing while the valve remains seated. The NPT 1-1/4" connection ensures a tight seal, and the robust carbon‑steel body tolerates high‑pressure environments.
Key System Performance Baselines:
- Leak Prevention: Maintains a seal under pressures up to 150 psi.
- Serviceability: Enables isolation without depressurizing the entire loop.
- Compatibility: Fits standard 1-1/4" NPT connections on Bell & Gossett units.
⚠️ Application Profile: Ideal for commercial boiler systems, chilled‑water loops, HVAC heat exchangers, and any hydronic circuit requiring reliable back‑flow protection and easy maintenance.
