HVAC Valves

HVAC valves are fundamental parts of an HVAC system particularly when it concerns the functionality of a heating and cooling unit. These valves are housed together with the most hard working components of the system within the inside unit. The main function of HVAC valves is to control the temperature, pressure, flow or liquid level in the involved mechanisms of an HVAC system. HVAC valves can be open or closed by means of an electrical, pneumatic or hydraulic controller system.

Sizing HVAC Valves

For a stable operation, make sure that the HVAC valves are correctly sized and meet exactly the requirements of the system. The valves must be just the right size to allow near to full opening during the required maximum flow of load conditions. If the HVAC valves are too large for the system, there may be function issues when the operating range reaches its extreme low end.

Valve Failures

HVAC valves are meant to balance the flow and at the same time, to isolate system portions for maintenance. One problem that is common with system HVAC valves is ineffective blocking of the water flow. Here, HVAC personnel have to stop the operation and shut down the system even for repair of such minor problems. Another usual HVAC valve problem is the occurrence of leaks. These two system valve issues can be easily resolved with HVAC valve replacement.

When system troubles frequently arise concerning HVAC valves, it is better to have the system replaced with a new one than to have it constantly repaired.
