Product Overview
The Danfoss ETS 400 (model code 034G3502) is a high-precision electronic expansion valve (EEV) engineered for advanced refrigerant flow control in commercial and industrial refrigeration, air-conditioning, and heat pump systems. As a stepper-motor-driven expansion valve, it provides continuous, highly accurate modulation of refrigerant mass flow in response to superheat and system demand signals from a dedicated electronic controller. Unlike thermostatic or mechanical expansion devices, the ETS 400 delivers fast, repeatable positioning across its full stroke, enabling optimized evaporator performance, improved energy efficiency, and stable operation across wide load ranges. It is a core component in modern process cooling and climate control architectures where precise metering and rapid response are essential.
