GENERAL INSTALLATION INSTRUCTIONS
Install a Y-Type or equivalent strainer upstream
of the Type B. The built-in strainer screen is
secondary protection only.
The Type B regulator should be installed in the
horizontal position with the spring chamber up
or down. For other installation requirements
consult the factory. For ease of operation and
maintenance, it is suggested that manual
shutoff valves be installed upstream and
downstream from the valve. Before installing
the valve, the piping and the valve should be
thoroughly flushed out to remove any foreign
material. Install the valve with the inlet pipe
fitted to the inlet connection identified on the
valve body. Use a good pipe joint compound on
the male pipe threads and do not over tighten
the valve connections.
CONSTRUCTION
Bronze body, internal trim, and diaphragms;
Teflon seat, diaphragm gasket, and bottom
plug gasket; stainless steel pressure spring.
All parts are commercially cleaned for
oxygen service.
