Two-position applications: the valve is normally sized to be the same as the pipe, using the largest Cv available for a given pipe size.

Modulating applications: select the valve to meet the BtuH requirements of the coil.

Assumptions:

  • The table assumes an atmospheric return.
  • Minimum coil BtuH calculated assuming a pressure drop across the valve of 50% of supply pressure.
  • Maximum coil BtuH calculated assuming a pressure drop across the valve of 80% of supply pressure.
