Question 23

Why should architects and building engineers select a new HVAC system using R410a – a non ozone-depleting refrigerant?

Accepted Answer

Because by selecting R-410a you eliminate the possibility that refrigerant leaking from your system will contribute to the hole in the ozone layer. R410A contains no chlorine, it is ozone and climate responsible. Plus, R410a allows higher efficiencies than R22, it not only makes sense environmentally — it also makes sense from an economic standpoint, too!

Question 24

What is the US Governments position on R410a?

Accepted Answer

Production of R22 in the United States is scheduled for termination in 2015. R410a is the best alternative to R22 available today.

Question 25

Why do HVAC systems using R410a need special high pressure valves?

Accepted Answer

Systems using R410a refrigerant operate at pressures approximately 1.6 times higher than systems using R22 or R407c. Water cooled systems, utilizing R410a refrigerant, demand special regulating valves to manage the heat transfer process.

Question 26

What if we have a special R410a control valve requirement?

Accepted Answer

Metrex has many off-the-shelf R410a high refrigerant pressure regulating valve solutions. Our experienced engineers can design or modify existing valves to meet all your R410a system requirements.

Question 27

Can I get valves for more than 150 psi inlet?

Accepted Answer

Of course! See either Commercial & Industrial Buildings & Products or High Pressure Water Sides.

Question 28

Can I get valves with high refrigerant R410a?

Accepted Answer

Indeed! See either Standard Service or High Refrigerant Pressure valves.

Question 29

How do I size a valve?

Accepted Answer

If you know how many gpms you need, divide it by the Cv squared (Cv2). Or, check out one of the following: Metrex Matrix, About Our Valves or Sizing A Valve.
