Temperature
Operating Range: 32° to 220° F (0° to 104°
C).
Installation:
The 125, 250 and 375 series can be mounted
in any position. The 500 and 750 series can be mounted
in any position except with the outlet port down. We
suggest the unit be calibrated in the attitude in which
it will be installed. An actuation point approximately
3 or 4 times normal flow rate should be chosen to avoid
the valve actuating from initial pressurization of the
system and normal surges. If flow is kept constant,
an actuation point 10% above the normal rate may be
used.
