The port sizes are usually not much different if at all. In the case of our Sporlan valves the port sizes are the same between 410A and R22. An internally equalized valve should never be substituted for an externally equalized valve.

The TXV determines which refrigerant can be used with a coil. Most new coils can be used with either Ror R410A providing that the correct TXV is used. A TXV can also be added to a piston type coil to improve efficiency. The integral check valve means fewer connections, easier installation, and increased reliability. The Sporlan TEVs designed for R- 410A have replaceable thermostatic elements designed for the higher pressures associated with R- 410A.
