Fema DWR16-206 pressure switch

Honeywell Fema DWR16-206 pressure switches designed for steam, hot water, fuel gases, and liquid fuels. Honeywell DWR16-206 pressure switches developed and certified to operate with gases according to DVGW G260 specifications and EN 1854 sealing criteria. However, it is essential to conduct a chemical resistance test before selecting the device.

The standards include EN 13611 and DIN EN 1854, while the directives encompass EU/2009/142/EC (GAD) and EU/94/9/EC (ATEX).
