Specifications for safety shut-off type 1800B
Safety shut-off type 1800B
The Elster safety shut-off type 1800B is intended for the medium pressure segment. These types of safety shut-offs have been used extensively in HAS installations.
In combination with the safety shut-off type USSA we have two different constructions in our product line therefore we are able to supply both safety devices for HAS sets. The Type 1800B is from the brand Elster-AMCO and is fitted as standard on a gas pressure regulator type 1800-B2. This type is only available for overpressure (OPSO).
Due to the modular design, this safety shut-off can also be combined with a dust filter. The filter / OPSO set is a combination of the following types of safety devices and the small dust filter type DF.
