Description
Cata-Dyne AC-TC-8000N-7 thermostat control valve (8,000 Nat Gas 7wc).
This valve is designed with a bulb and capillary assembly that automatically regulates fuel flow to a Cata‑Dyne™ heater from 100% when heat is required to approximately 30% when the thermostat is satisfied.
This unit is used to control building temperature for spot and space heating applications. The sensing bulb is filled with a temperature sensitive liquid. Changes in the temperature at the bulb expand and contract the liquid on temperature rise and fall causing the internal mechanism to modulate the flow of fuel.
