VPI Series Pressure Independent Control Valves

The new Honeywell VPI Pressure Independent Control Valves and Actuators integrates the flow, pressure and temperature control functions in a single valve and then automatically controlling the flow in each hydronic system circuit to maintain temperature and comfort when pressures fluctuate.

Selecting, installing and commissioning Honeywell VPI Pressure Independent Control Valves and Actuators is a quick and cost-effective process. The valves feature an integrated flow regulator with rolling diaphragm that delivers flow balancing and control functions in one package. And there’s no Cv calculation required — just pick the valve that matches the flow requirements. Honeywell makes it that easy. The VPI Pressure Independent Control Valves & Actuators include an innovative self-adjustment feature which allows continuous self-balancing in all valve positions. This ensures that each thermal unit controlled by a valve is always supplied with the exact flow required for the specific system condition.

• Compact one-unit PICV, including modulating control valve, dynamic flow limiter and differential pressure control valve in one body.
• Easy setting and Field adjustable – flow setting is stepless and can easily be set to any design flow in the flow range. Setting can be done before or after installation and flow may be changed on demand without removing the valve from the installation
• “Sealed” setting - actuator will cover the setting and protect against tampering
• Standard or failsafe actuator; always incl. feedback signal - an easy solution for designers, installers and end-users
• Honeywell VPI series PICVs combine 3 functions into one valve body:
• 1. Control valve
• 2. Differential pressure controller that protects against
• pressure fluctuations.
• 3. Presetting scale to set the desired max. flow
• Sizes from DN15 to DN50 with female threaded connections and DN50-250 with flanged connections.
• Controls chilled or hot water with up to 50% glycol.
• Flow balancing in valve body through diaphragm.
• Higher presetting precision due to step less analogue scale with 41 Max. flow setting trough dial on valve body
• Electrical actuators with selectable control modes, Linear or Equal percentage
