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!
Production of R22 in the United States is scheduled for termination in 2015. R410a is the best alternative to R22 available today.
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.
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.
There are no gaskets. Isolate the water supply, unscrew the old bellows and replace with new bellows. See our Valve Rebuild Kits page.
No, isolate the water supply.
