General

VPI series PICV and actuators make it simple to achieve 100% control of the water flow in the building while creating high comfort and energy savings at the same time. An additional benefit is that no balancing is required if further stages are added to the system, or even if the dimensioned capacity is changed. Honeywell’s VPI series provides modulating control with full authority regardless of pressure fluctuations in the system.

Features

Designed to use in heating and cooling systems such as Air Handling Units, Fan Coil Units, and other central plant applications.

Flow setting is step-less 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.

Compact one-unit PICV, including modulating control valve, dynamic flow limiter and, differential pressure control valve in one body.

It combines an externally adjustable automatic balancing valve, a differential pressure control valve and, a full authority modulating control valve in a single unit. It combines 3 functions into one valve body.

Actuator will cover the setting and protect against tampering.

Higher presetting precision due to step-less analog scale with 41 Maximum flow setting through the dial on the valve body.

Shut-off leakage as per ANSI / FCI 70-2 206 / IEC 60534-4 - Class IV/ 0.01% leakage of full open valve capacity.  Tested as per BSRIA standards.  UL & CE approved actuators.

Two-way, modulating to accept digital or analog input signals. The valves accept 0(2)-10V, 3-point floating or ON/OFF input signals.

Flow balancing in valve body through diaphragm.
