Two Way Distributing Valve Rotary Discharge Valve

The HVAC industry relies on the automated control of hot and cold air, water, and hydronic heat transfer fluids or refrigerants through complex piping systems, ductwork, and heat exchangers. As one of the important accessories in HVAC industry, the valve is a control component in the fluid conveying system. It has the functions of cut-off regulation and diversion to prevent countercurrent pressure stabilization and diversion or overflow and pressure relief.

As a professional valves wholesale, MstnLand's HVAC control valves are critical components in an end-to-end system, and their efficiency is an important factor in overall system efficiency. Choose from thousands of valve and actuator combinations that are built to deliver efficient, dependable, long-lasting and leak-proof performance.

Applications of hvac control valves

The HVAC industry relies on the automated control of hot and cold air, water, and hydronic heat transfer fluids or refrigerants through complex piping systems, ductwork, and heat exchangers. HVAC systems are sophisticated circuits composed of different parts, and each of these contributes to the control of environmental conditions. In an AHU system, accessories such as the valves have an important role in the execution of the inputs sent from the controllers and support from other devices such as, for example, the actuators.

The role of valves in HVAC systems

HVAC control valve is a tool used to manage and control the direction of a given flow, of a gas or a liquid. Even though its usage is common in different areas and industries, in the HVAC systems, valves are mainly applied to manage the flow of fluid inside the pipes. Their opening and closing motion regulates the flow following the indication of the air handling unit and the AHU controllers. The capacity of opening and modulating the aperture of the pipe at different levels depends on the type of the valve, its specifications and the other devices involved in the task such as the actuators.
