These Valves may be mounted in any position and use the proven expanding wax principle to actuate the 3-way temperature element assemblies. The model H Valves may be used for diverting or mixing service. They make very economical temperature limiting Valves to prevent scalding in home, motel or hotel hot water supply systems. Radiant heating systems can use these Valves in limiting water temperature to prevent surface cracking and over-heating of plastic piping. Other applications include electronic and battery cooling circuits, pump temperature relief Valves etc.

3 LeakholesIn some applications, it is necessary to have leak holes drilled in the element to ensure a small flow between ports A and C. Leak holes are available in sizes ranging from to 19mm (1/4 to 3/4 ). Please refer to the Temperature Control Valve Temperature settingsA wide selection of element materials, seals, and temperatures are available. Follow the equipment manufacturers guidelines for heating/cooling systems. Temperature settings are available from 13 C to 116 C (55 F to 240 F). Refer to the Temperature & Element Characteristics table on page 6 for specific temperature settings. In general the temperature quoted is the nominal operating temperature in diverting mode on water systems. For long life, AMOT Valves should not be operated continuously at temperatures in excess of 14 C (25 F) of their maximum continuous rating. If this condition is anticipated then consult AMOT for suitable alternatives. Element materialsl Bronze, brass and stainless steell Nickel plated/Stainless steel Available housing materials l Steell Stainless steelFor mixing and oil circuits the temperature may be one to two degrees higher due to flow, viscosity and other system parameters.

4 Elements and seals are available in a variety of materials. These materials are suitable for most applications. Please refer to the Temperature Control Valve Selection Guide (Datasheet_Temp_Control_Valve_Guide) for material compability Guide (Datasheet_Temp_Control_Valve_Guide) to determine the hole size required for specific materialsl Buna-N/Nitrilel Vitonpage 4 Thermostatic Control Valves - Model H Datasheet_H_Thermostatic_Control_Valve_0 812_Rev4 When Valves are used for diverting service, the inlet is Port A (temperature sensing port), with Port C being connected to the cooler, and Port B connected to the cooler by-pass ApplicationsApplicationsValve as shown maintains minimum flow through cooler to conserve water.

8 An inspection at two or three year intervals is adequate to detect and make provision for normal wear. The frequency of element replacement will depend on the operating conditions and the type of fluid being controlled. Because of the diaphragm and plug construction of the wax actuated element, calibration will be maintained over thousands of cycles. Whenever elements are replaced, the O-ring seals should also be replaced. For convenience, elements and O-ring seals may be ordered together in the service kits listed below.
