Thermostatic Control Valve Working Principle

Thermostatic valves working principle thermostatic valves are used for the infinite proportional regulation of flow quantity depending on the setting and the sensor temperature.

Thermostatic control valve working principle.

In this article we ll be learning how thermostatic expansion valves work. The storage of water at high temperature removes one possible breeding ground for legionella. Thermostat working principle thermostat is a device which is used to maintain a desired temperature in a system like refrigerator air conditioner iron and in a number of devices. The only difference is that the control valve helps to maintain the temperature of a desired process at a specific level.

A valve that is part of the thermostatic valve element and is operated thermostatically can be a simple but reliable control solution. They operate without the supply of auxiliary energy such as electricity or compressed air. The valves are self acting i e. Also the valve does not need electricity or control air.

Thermostatic valves consist of a series of industrial products that are used for cooling and heating control. It is often abbreviated as tcv temperature control valve in most process drawings and p ids. A temperature control valve is just like any other control valve. The expansion valve is an essential component in almost every refrigeration cycle and the thermostatic expansion valve is the most commonly used within hvac systems.

These valves may be mounted in any position and use the proven expanding wax principle to. Thermostatic control valve model b datasheet b thermostatic control valve 1119rev17 page 3 overview amot model b thermostatic valves are available in a wide selection of sizes and settings to fill a multitude of fluid temperature control requirements. Commonly used in washdown applications these systems include a temperature regulating valve with an internal check valve and vacuum breaker to prevent backflow two ball valves for manual control of the water supply a dial thermometer that displays the outlet temperature and a hose rack for storage. The above animation shows how a horne thermostatic mixing valve or tmv works to proportion the mix of hot and cold water to provide blended water at a set te.

The use of a thermostat rather than a static mixing valve provides increased safety against scalding and increased user comfort.
