Thermostatic Valves
Thermostatic valves are a simple and reliable control solution requiring neither electricity nor control air. An example of application is automatic control of water temperature in cooling systems.
The valves are available with remote or built-in sensor.
AVTA thermostatic valves are widely used for temperature control in many different sorts of equipment and installations where cooling is required. – Self-acting thermostatic valves for accurate cooling flow control based on sensor temperature – Capillary sensor with adsorption charge, mass charge or universal charge, depending on application. – Open on rising temperature. – Brass or stainless steel valve body.
The charge is a mix of liquid and gas where the liquid surface (sensingpoint) is alway inside the sensor. The sensor can be installed colder or warmer than the valve. |
