US 2026/0049667 A1 · FAST FILL VALVE FOR CLOSED LOOP FLUID SYSTEM

Abstract

A fluid control system with a fast fill valve for expedited filling and draining of closed-loop systems allowing for temporarily opening the loop to allow filling without a separate vacuum process The valve operates in two positions: an open position for rapid, unidirectional fluid ingress and passive air egress and a closed position for a secure, sealed state during normal operation. Some embodiments include vacuum assisted air egress in parallel with filling.
