What HVAC means?
Heating, Ventilation, and Air Conditioning
HVAC stands for heating, ventilation, and air conditioning.
What is an HVAC Valve?
HVAC valves are used to control flow in pipes. Major components of an HVAC system such as water chiller, cooling water pumps, air handling units, and fan coil units use valves to control the flow of water, gas, and air.
What are the Different Types of HVAC Valve?
A pressure reducing valve is used to reduce the pressure of the water in the HVAC hydronic loop while circuit setter valves are used to maintain a set amount of flow through a piping loop.
Balancing valves maintain flow conditions so that control valves function properly in HVAC systems because unbalanced systems can produce wide temperature variations among rooms and can increase energy needs. We offer a line of balancing valves that help to heat and cooling systems perform well and cost-efficiently.
On a centric (concentric) butterfly valve the stem is centered in the middle of the disc and the disc is centered in the bore. The eccentric butterfly valve has one or more stems (stub shafts) located offset from the center according to the categories of double and triple offset valves.
