##**A Guide to HVACR Valve Types and Manufacturers**
Navigating the world of Heating, Ventilation, Air Conditioning, and Refrigeration (HVACR) systems can be daunting, especially when it comes to the countless number of valves used to
control the flow of fluids and gases. These valves are crucial for the efficient operation of HVACR systems, ensuring comfort, safety, and energy efficiency.
Whether you're a seasoned professional or new to the HVACR field, understanding the different types of valves and their applications can help demystify these essential components. Let's
explore the main types of valves used in HVACR systems and highlight some of the leading manufacturers for each type.
**1. Ball Valves**
Description: Ball valves use a spherical disc to control flow. When the valve is open, the hole in the ball is in line with the flow. When closed, it's perpendicular, blocking flow. They offer
durability and
excellent shut-off capabilities, making them a
popular choice for systems requiring tight control.
Applications: Widely used in refrigeration, heating and air conditioning systems for shut-off and control applications.
Leading Manufacturers: Emerson, Danfoss, Honeywell, and Johnson Controls are notable manufacturers offering a range of ball valves designed for HVACR applications.
**2. Globe Valves**
Description: Globe valves, characterized by their spherical bodies and internal baffle, regulate flow in a pipeline. They provide precise control over flow rate and are typically used in
applications where flow
needs to be adjusted regularly.
Applications: Ideal for modulating flow control in hot and cold water systems, steam applications, and other fluid control scenarios in HVAC systems.
Leading Manufacturers: Siemens, Honeywell, Johnson Controls and Schneider Electric are key players producing globe valves that are well-suited for HVACR applications, offering reliability
and precision.
**3. Solenoid Valves**
Description: Solenoid valves are electrically operated devices that open or close to control the flow of liquids or gases. They are known for their quick response times and are used where control is needed
electronically.
Applications: Common in refrigeration systems to control the flow of refrigerant or in air conditioning systems for controlling water flow.
Leading Manufacturers: Danfoss and Parker Hannifin are leading manufacturers, offering a wide range of solenoid valves designed for precise control in HVACR systems.
**4. Butterfly Valves**
Description: Butterfly valves use a rotating disc to control flow. They are known for their compact design and low-pressure drop, making them suitable for large diameter applications where space is a
concern.
Applications: Frequently used in large HVAC systems, including chillers and air handling units, for regulating and isolating flow.
Leading Manufacturers: Belimo and Bray are renowned for their high-quality butterfly valves, providing efficient and reliable flow control solutions for HVACR applications.
**5. Check Valves**
Description: Check valves, or non-return valves, allow fluid to flow in one direction only, preventing backflow. They are crucial for maintaining the directionality of flow and protecting equipment.
Applications: Essential in HVACR systems to prevent reverse flow, which can damage equipment and disrupt system operation.
Leading Manufacturers: Watts offers a variety of check valves designed to meet the specific needs of HVACR systems, ensuring protection against backflow.
**6. Pressure Relief Valves**
Description: Pressure relief valves are safety devices that release excess pressure from a system to prevent damage or explosions. They are set to open at a predetermined pressure level.
Applications: Used in refrigeration systems to protect against overpressure conditions, ensuring system safety.
Leading Manufacturers: Emerson and Johnson Controls are known for their reliable pressure relief valves, providing an extra layer of safety in HVACR applications.
Understanding the various types of valves and their applications within HVACR systems is crucial for wholesale distributors when selecting the right components for any project. Each type
of valve offers unique benefits suited to specific system requirements, and the leading manufacturers mentioned provide high-quality options that professionals can rely on.
Whether you're designing a new system or maintaining an existing one, having a solid grasp of valve types and their manufacturers can help ensure your HVACR system operates efficiently
and effectively.
