Our genius is valves ®

In order to control the temperature on the secondary side, a control valve is installed on the primary side and will modulate in response to temperature demands communicated from sensors on both sides of the unit.

Recommended Solutions

Crane Fluid Systems has a number of applicable solutions available for this type of terminal. See examples below.

PICV has become the preferred solution for many designers and installers in recent years. However, the option of using the traditional DPCV method is still available and can suit certain applications.
