Installation
On steam service, the regulator should be installed with the
actuator down so that the diaphragm will be protected by a
condensate barrier. If installed otherwise, an adequate
condensate barrier must be incorporated.
In the Spring Diaphragm Actuators, the 1/2" NPT pressure
connection is located on the upper diaphragm case (13).
