HONEYWELL VPI Series Pressure Independent Control Valve Diagprahm

- 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.
- Automatic balancing eliminates overflows, regardless of fluctuating pressure conditions in the system.
- Close-off pressure range up to 800 kPa.
- Shut-off leakage as per ANSI / FCI 70-2 206 / IEC 60534-4 - Class IV/ 0.01% leakage of full open valve capacity.
- Differential pressure operating range up to 800 kPa.
- High flows with minimal required differential pressure due to advanced design of the valve
- Electronic fail-safe actuators also available for sizes.
- Available with and without Pressure test ports.
- Two-way, modulating to accept digital or analog input signals. The valves accept 0(2)-10V, 3-point floating or ON/OFF input signals.
- Simple Maintenance – Internal parts can be accessed without removing the valve housing from the piping lines.
