Danfoss 023Z1013 DAS 305 Drayer – Dry‑Expansion Valve

The Danfoss 023Z1013 DAS 305 Drayer is a dry‑expansion valve specifically engineered for cooling and HVAC circuits that require precise pressure regulation. It controls the pressure drop of low‑pressure refrigerant entering the evaporator, improving system efficiency while providing over‑pressure protection. With a flow capacity ranging from 0.5 to 30 kg/h, it maintains stable operation even in multiple parallel lines. The valve body is forged from high‑strength steel and equipped with stainless‑steel fittings for long‑term durability. Installation is straightforward thanks to standard DN15‑DN50 connections and materials compliant with ISO‑14644‑1 clean‑room standards, making it ideal for industrial and data‑center environments. An integrated pressure sensor and adjustable flow control allow operators to quickly adapt to various refrigerants (R‑134a, R‑410A, R‑404A, etc.) and changing operating conditions. Danfoss backs the product with a 10‑year warranty and comprehensive technical support, enhancing reliability and ROI. In large‑capacity cooling towers, water‑cooled chillers, industrial refrigeration loops, and data‑center HVAC units, the DAS 305 Drayer optimizes performance, reduces energy consumption, and lowers maintenance costs.
