Frese STBV VODRV

Manual Balancing Valve

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

The Frese STBV 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 handwheel to set point 0.0 and reopened to the previous set point.

Benefits

• Simple to install and adjust
• Clear, 2 digit pre-setting scale
• Isolation feature
• Provides an alternative to commissioning sets (only one valve to install instead of a separate Frese STBV DRV and metering station)
• Delivers accurate control of the flow at all settings

Features

• Available in sizes DN15 to DN500
• Double regulating feature allows the valve opening to be set and locked at the desired set point using a 3 mm allen key
• Built in PT ports for flow measurement
• Can be installed with the PV Compact differential pressure control valve for efficient pressure and flow control
