PRODUCT DESCRIPTION
The Type 743 is a second-stage low pressure regulator suitable to
be installed in double stage domestic installations up to 15 Kg/h
capacity. The type 743 reduces the pressure at the outlet from the
1st stage directly to the utilization pressure of the final appliances.
Furthermore, it is possible to set up manually the outlet pressure.
This regulator cannot be used as single stage regulator, but always
has to be installed after a 1st stage regulator.
See diagram schematic: D-25 (page C13) for installation system.
