Valve

A valve is a mechanical device used to control, regulate, or direct the flow of liquids, gases, or other substances within a system or pipe. In the HVAC and AC industries, valves are critical components in controlling refrigerant flow, managing pressure, and regulating temperature within heating, ventilation, and air conditioning systems. Common types of valves used include ball valves, check valves, expansion valves, and pressure relief valves, each designed for specific functions to maintain the efficiency, safety, and performance of HVAC systems. Valves help ensure proper system operation, prevent leaks, and provide the flexibility needed for effective temperature and pressure control.
