Frese STBV Range

VODRV - DN15-DN500

The Frese VODRV is a Variable Orifice Double Regulating Valve for flow balancing and verification.

The Frese VODRV is ideally suited for use in heating and cooling applications for the balancing and accurate verification of flow in various sections of the system.

The VODRV balancing valve ensures simple and reliable verification of the system and can be installed in both variable flow systems and constant flow systems.

The double regulating valve feature allows the valve to be set to the required position and locked thus limiting the opening of the valve. If required, the valve can then be isolated by turning the hand wheel to set point 0.0 and reopened to the previous set point.
