Models I-1284 and I-1285

The I-1284 and I-1285 thermostatic valves are compact, self-contained and self-powered, three-way temperature regulating valves. They are particularly suitable for controlling water and lubricating oil temperatures on internal combustion engines.

I-1248

Model I-1248 Temperature Regulator

The I-1284 Temperature Regulators are compact, self-contained and self-powered, three-way control valves especially adaptable to control of water and lubricating oil temperatures on internal combustion engines. The POWER PILL® element, located inside the poppet assembly, responds to the temperature of the medium surrounding it and provides the force necessary to position the poppet as the temperature of the liquid passing through the valve changes. Temperature regulation is achieved by the proportional action of the three-way valve which varies the amount of medium through or bypassing the cooler to maintain the desired temperature. Operation of the POWER PILL elements is unaffected by pressure changes in the system.

The POWER PILLS are factory-set for the specified control temperature and are not manually adjustable. By exchange of POWER PILL elements, the operating temperature may be changed in a very simple manner. Since all internal parts lift out with the valve bonnet, it is not necessary to remove the valve from the piping.

The I-1284 series is equipped with a quick-acting manual operator which permits overriding the thermal element if and when abnormal load, conditions are encountered in the system.
