PRODUCT DESCRIPTION

The Type 753B2 is a second-stage low pressure regulator suitableto be installed in double stage pressure regulated domestic instal-lations. This regulator cannot be used as single stage regulator,but always has to be installed after a 1st stage regulator. The type 753B2 reduces the pressure at the outlet from the 1ststage directly to the utilization pressure of the final appliances.Furthermore, it is possible to set up manually the outlet pressurefrom 22 to 50 mbar.See diagram schematic: D-14 and D-24 (page C07, C12) for instal-lation system.

PRODUCT DESCRIPTION

The type 738BP is a second stage regulator manufactured accor-ding to the standard requirements of UL 144 and NFPA 58. This regulator cannot be used as single stage regulator, but alwayshas to be installed after a 1st stage regulator. This regulator reduces the pressure at the outlet from the 1st stagedirectly to the utilization pressure of the final appliances (11” wc). Furthermore, it is possible to set up manually the outlet pressurefrom a minimum value of 9" w.c. to a maximum value of 13" w.c.The type 738BP is suitable to be installed in double stage pres-sure regulated domestic installation. See diagram schematic: D-25(page C13) for installation system.

PRODUCT DESCRIPTION

The type 738MP is a second stage regulator manufactured accor-ding to the standard requirements of UL 144 and NFPA 58. The type 738MP is a second stage medium pressure regulator,suitable to be assembled in installations requiring 3 regulationstages.This regulator reduces the pressure at the outlet from the 1st stageto a medium pressure (2 PSI). Generally, after the regulator type738MP it is necessary to install a stabiliser, in order to keep a con-stant pressure of 11" wc. The type 738MP is suitable to be instal-led in double stage pressure regulated domestic installations. See diagram schematic: D-28 (page C14) for installation system.
