Float valves

Valve sealing integrity under static and dynamic pressure is maintained using high-compression elastomer seats or precision-lapped metal-to-metal seals. These components are tolerance-matched to within microns to ensure consistent contact under varying temperature and pressure conditions. Float valves are designed to maintain shutoff performance under backpressure scenarios, typically tested to ANSI/FCI 70-2 Class VI leakage standards. Seals retain dimensional stability across wide thermal cycles and differential pressure zones. 

Actuation is inherently mechanical and self-regulating. Valve operation continues during power failure or sensor malfunction, offering a deterministic response to fluid level changes. Mechanical stiction and hysteresis are minimized through low-friction pivot assemblies and linear float guidance systems. Designs often include secondary containment floats or dual-arm redundancies for critical systems, enabling fail-safe closure even in the event of primary float degradation.
