Emerson Asco Solenoid Valve Series 210 Hung Diaphragm Stainless Steel

Pilot Operated, Hung Diaphragm

The Emerson ASCO 210 Series stainless steel hung diaphragm pilot operated solenoid valve is a premium-grade, 2-way solenoid valve designed for reliable on/off control of aggressive, corrosive, and high-purity fluids in demanding industrial environments. Manufactured by Emerson ASCO, a global leader in fluid automation, the 210 Series in stainless steel delivers exceptional durability, chemical resistance, and long-term operational stability for critical process applications.

This hung diaphragm solenoid valve utilises a pilot-operated operating principle to achieve high flow rates with minimal power consumption. The suspended (hung) diaphragm design ensures superior sealing, reduced mechanical stress, and smooth actuation across a wide pressure range. The precision-machined stainless steel body provides outstanding resistance to corrosion, making this solenoid valve suitable for harsh media, washdown environments, and hygienic processes. The valve is available in normally closed and normally open configurations with multiple orifice sizes and threaded or flanged connections depending on model selection.


Key Advantages

  • Corrosion-resistant stainless steel construction for aggressive and hygienic media
  • High flow capacity with pilot operated solenoid valve design
  • Reliable hung diaphragm sealing system for long service life
  • Low power consumption with consistent switching performance
  • Wide pressure and temperature capability
  • Backed by the proven quality and global support of Emerson ASCO

Typical Applications

The Emerson ASCO 210 stainless steel solenoid valve is widely used in industries requiring high cleanliness, chemical resistance, and reliability, including:

  • Chemical processing and refineries
  • Food and beverage production
  • Pharmaceutical and biotechnology manufacturing
  • Water treatment and desalination plants
  • Steam, hot water, and aggressive fluid control
