Emerson Launches ASCO Series of Solenoid Valves

08 June 2021

Emerson recently revealed its new range of two-way and three-way solenoid valves — the ASCO Series 256/356. In this newest release, Emerson fulfills the industry’s growing need for more compact equipment without compromising fluid control performance. The ASCO 256/356 has a smaller footprint than other valves on the market, and consumes up to 40% less power while maintaining a 30% higher pressure rating. 

Emerson has optimized the valve body and internal flow path to produce a valve that is more efficient and requires less space. This enables OEMs to optimize the internal layout of their equipment, allowing for high-performance fluid control options to be incorporated into smaller final products. This is of particular importance to manufacturers of coffee machines, heating equipment, air conditioners, analytical and medical devices, pumps, and compressors. 

The increased pressure rating of some versions of the ASCO Series 256/356 also enables them to be utilized in more demanding applications, such as high-pressure washers and hydrogen fuel dispensers. Emerson has also made improvements to the DC voltage version of the new series, which is now similar to that of the AC voltage version. This reduces overall system costs by eliminating the need to convert to AC power when maximum solenoid valve performance is required. 

The ASCO Series 256/356 offers an expanded selection of body materials and connection options. Material options include stainless-steel, lead-free brass and an engineered composite material that is 20% lighter than brass. The valves meet global health and safety standards for food and beverage applications and are IP67-rated, meaning they are dust-tight, and submersible in up to 1 m of water.
