Control Valves

Honeywell threaded pressure independent control valves are used in heating and cooling systems such as Air Handling Units, Fan Coil Units, and other central plant applications. Honeywell VPI series provides modulating control with full authority regardless of pressure fluctuations in the system. Honeywell VPI series combines an externally adjustable automatic balancing valve, a differential pressure control valve and a full authority modulating control valve in single unit.Honeywell VPI series makes 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 if the dimensioned capacity is changed. Energy saving due to optimal control, lower flow and pump pressure. Maximized ΔT due to faster response and increased system stability.

FEATURES
• Compact one-unit PICV, including modulating control valve, dynamic flow limiter and differential pressure control valve in one body.
• Available in DN female threaded (ISO) sizes varying from DN15-50.
• 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 maximum flow
• Controls chilled or hot water in closed loop systems with up to 50% glycol.
• Flow balancing in valve body through diaphragm.
• Higher presetting precision due to step less analogue scale with 41 Maximum 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 kPaD.• 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.
