Danfoss 068Z3405 Valve 328140-751 This assembly effectively purges theThe Danfoss 068Z3405 (TES2) is a high performance thermostatic expansion valve engineered for precise refrigerant injection into evaporators. Designed specifically for R404A R507 systems, this valve utilizes an external equalization connection (1 4 in. flare) to compensate for pressure drops across the evaporator, ensuring optimal superheat control. The 3 8" x 1 2" flare connections allow for straightforward installation and field replacement in
