Fema DWR6-313 pressure switch

Honeywell Fema DWR6-313 pressure switches designed for use with steam, hot water, fuel gases, and liquid fuels. Fema DWR6-313 differential pressure switches developed and certified for working with gases in accordance with DVGW G260 specifications and EN 1854 sealing standards. Honeywell DWR6-313 pressure switch can only be used within the electrical, hydraulic, and temperature ranges specified in the technical data table. The high-quality stainless steel components of the sensor, which come into contact with the working medium, allow Honeywell DWR6-313 differential pressure switch to be used in various environments. However, it is essential to conduct a chemical resistance test before selecting the device.
