Thermostatic Control Valve Working Principle

These valves may be mounted in any position and use the proven expanding wax principle to.

Thermostatic control valve working principle.

The valves are self acting i e. They operate without the supply of auxiliary energy such as electricity or compressed air. The use of a thermostat rather than a static mixing valve provides increased safety against scalding and increased user comfort. 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.

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. Thermostatic valves consist of a series of industrial products that are used for cooling and heating control. A valve that is part of the thermostatic valve element and is operated thermostatically can be a simple but reliable control solution. You can watch the video tutorial on this article by scrolling to the bottom of the page.

A thermostatic mixing valve tmv is a valve that blends hot water with cold water to ensure constant safe shower and bath outlet temperatures preventing scalding. A temperature control valve is just like any other control valve. It is often abbreviated as tcv temperature control valve in most process drawings and p ids. Also the valve does not need electricity or control air.

In this article we ll be learning how thermostatic expansion valves work. Thermostat works on the principle of thermal expansion of solid materials. 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 only difference is that the control valve helps to maintain the temperature of a desired process at a specific level.

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