GENERAL
DESCRIPTION
These regulators
are simple, self-contained instruments that control cooling applications
by regulating the flow of cooling water in accordance with discharge water
temperature. They are applicable to plastic molds, die casting molds,
small condensers, air compressors, etc., where the volume of cooling water
required is within the capacity limits of the regulators. The 908-A design
saves water.
OPERATION
When the
discharged cooling water reaches a predetermined temperature at the
thermostat, the thermostat moves to gradually open or close the valve port
to allow more or less water to flow through the equipment being cooled. An
adjustable bypass for constant flow is included in the design.
SETPOINT
TEMPERATURE RANGE
The 908-A can be
set to control at any point within the adjustable setpoint range.
Available from stock are:
3/4" 908-A
50-115° F. and 100-160° F.

F. and 100-160° F.
Other ranges
available on quantity orders.
MATERIALS
All parts are
made of brass or bronze except the bellows which is made of phosphor
bronze. Packless construction. Eliminates the need for maintenance. End
connections are female threaded.
