Description
The Trane VAL20681 Liquid Line Service Valve O-06-06 isolates flow along the liquid line of a refrigeration circuit. A quarter-turn ball mechanism rotates internally to open or close the passage, with a capped service port providing access for pressure measurement and charging during maintenance. Within split-system and packaged HVAC systems, it sits between the condenser and expansion part in air conditioning equipment, threading into existing line connections without additional fittings. At operating pressures, it maintains a leak-free seal across the valve seat, preserving refrigerant charge integrity during routine field operations.
