| FPE thermostatic valves utilize the principle of expanding wax,
which in a semi-liquid state undergoes large expansion rates within a relatively narrow
temperature range. The self-contained power element activates a stainless steel sliding
sleeve which provides positive three-way valve action. All FPE
thermostatic valves are factory set at predetermined temperatures; no further adjustments
are necessary. A wide range of temperatures are available for water and oil temperature
applications. On starting, the total fluid flow is in by-pass mode. As fluid
temperature rises to the control range, some fluid is diverted to the cooling system. As
fluid temperature continues to increase, more flow is diverted, and when in a fully
stroked condition, all fluid flow is positively directed to the cooling system. FPE
thermostatic valves may be used for either mixing or diverting applications. In normal
operation, fluid temperatures are controlled to within a few degrees.
Standard FPE theromostatic valve housings are made from high
quality grey iron castings; however, aluminum, steel, stainless steel and bronze housings
are available. |
