How do Hattersley's Thermal Circulation Valves work?
As the water flows through the Thermal Control Valve the thermal element senses the water temperature and adjusts its stem position in the seat to control the flow rate some valves include an isolation valve. When reacting to water temperature changes the valve never completely stops the flow.
