HVAC Industry Valves

The HVAC (Heating, Ventilation, and Air Conditioning) industry relies heavily on valves to control the flow of various fluids and gases within heating and cooling systems. These valves play a critical role in regulating temperature, pressure, and fluid distribution, ensuring optimal performance and efficiency of HVAC systems. Globe valves are versatile valves commonly used in HVAC systems for their precise flow control capabilities. These valves feature a globe-shaped closure mechanism that moves perpendicular to the flow, allowing for fine adjustments in fluid flow rates. Globe valves are often preferred for applications requiring accurate control of temperature and pressure within HVAC systems.
