AMOT Model 2470 is a 2-way self-actuated temperature regulating valve with external sensor. The valve senses temperature via an expanding-wax element, located external to the valve body. Flow through the valve is modulated or shutoff in response to the temperature sensed by the element which may be located in the fluid circuit being controlled or in a separate fluid circuit, as in remote sensing applications
The valve will open on rising temperature SET-POINT FOR THIS VALVE IS 100 DEGREES FAHRENHEIT
The highly reliable expanding wax-element encased in bronze retaining cup produces exceptional valve travel per unit of temperature change. Metal seats and O-ring seal of ethylene propylene rubber minimize leakage in steam applications.
Body housing of cast iron with bronze seats and sliding valve, and stainless steel element adapter provide rugged performance. When the sensed circuit is corrosive or fluid containment is necessary, stainless steel wells MUST BE USED.
MODEL 2470B(-)1 This valve opens as the sensed temperature rises above the set point, and closes as temperature falls. Valve seat of Buna-N rubber can withstand 125 psi liquid pressure in closed position. Commonly used in cooling water control.
To obtain maximum long life from the temperature element, the valve must not be operated continuously at more than 50 F above the opening point on the 2470B(-)1 If it is necessary to operate at a continuous over-temperature, the factory should be consulted for alternate elements. Limited field adjustment of temperature setting can be achieved by turning the Adjusting Nut located inside the valve. If a different temperature range is required after initial use of the valve, the Temperature Element must be changed and the valve re calibrated. If the valve gives an indication of sticking or binding, check O-ring for excessive swelling and replace if necessary.
