Efficiently manage thermal expansion and safeguard your domestic water system from damaging pressure fluctuations with the 1BN357LF Bell & Gossett PTA-210V expansion tank. Designed for demanding applications, this ASME-rated vessel ensures system integrity by providing a reliable space for water to expand as temperatures rise, effectively preventing relief valve discharge and component stress.
This unit features a heavy-duty steel shell housing a sophisticated diaphragm design. Inside, a food-grade, FDA-approved polypropylene liner and a high-performance butyl diaphragm work in tandem to completely isolate the water from the metallic shell, preventing internal corrosion and maintaining water quality throughout the system's service life.
Key System Performance Baselines:
- ASME Certified: Engineered to meet rigorous ASME pressure vessel construction standards for safety.
- Water Isolation: Utilizes a butyl diaphragm to prevent contact between potable water and the steel shell.
- Corrosion Resistance: Includes an FDA-approved polypropylene liner for long-term durability.
- Pressure Management: Designed to absorb expanding fluid to maintain optimal system equilibrium.
⚠️ Application Profile: Ideal for commercial domestic water heating systems, high-capacity plumbing circuits, and installations requiring ASME-compliant pressure protection for potable water supplies.
