Fema DWR06 pressure switch

Fema DWR06 differential pressure switches used for steam, hot water, fuel gases and liquid fuels. Honeywell Fema DWR06 pressure switch designed and approved for working with gases in accordance with the DVGW G260 specification and the criteria for the degree of tightening according to EN 1854. Honeywell Fema DWR06 pressure switch allowed to be used strictly within the ranges of electrical, hydraulic and temperature parameters specified in the technical data table. Due to the high quality of the stainless steel sensor parts in contact with the working medium, Honeywell DWR06 differential pressure switch can be used for a variety of media. However, it is necessary to carry out a chemical resistance test before selecting the device.

Fema DWR06 pressure switch technical data
