Pettinaroli UK – PEB92H.04 – 1/2″ X 850L/H

The pressure-independent control valve (PICV) combines the functions of a differential pressure controller, a regulating valve, and a 2-port control valve into a single body.

The EVOPICV incorporates a small diaphragm-type DPCV to maintain a constant differential pressure across an orifice and to provide a constant flow rate whilst the differential pressure remains within the valve’s operating limits.

Beyond these working pressures, the valve acts as a fixed orifice. Thanks to the new diaphragm technology, the valve can also work with very dirty water.
Making this orifice adjustable allows the valve to be pre-set and deliver a range of flow rates (unlike automatic balancing valves).

The presetting gear can be easily adjusted. It works by varying the control valve stroke.
The EVOPICV valve also includes 2-port temperature control using an oblique-pattern globe valve.

The globe valve plug is machined to provide a near-linear flow-control characteristic. Because the differential pressure across the valve seat is constant, the authority of this control valve is very close to 1.

Due to the way the EVOPICV valve controls the flow rate, balancing valves are not required, regardless of the differential pressure branch and sub-mains.

The flow rate is maintained at the terminal unit regardless of system conditions, making the valve ideal for systems with inverter-driven pumps.

The 92 series PICV valve offers the following functions:

• Good valve authority to maintain temperature control and power output from the terminal unit.
• Maximum design flow limitation: once set, the 92 valve maintains design flow regardless of pressure changes in the system.
• It can easily be set up once installed, using the setting ring (with no actuator on).
• Measure by means of specific meter of the differential pressure across the valve: in this way user can verify if the start-up pressure has been reached and overpassed.
• DPCV dirt-resistant: the valve works during and after a Contaminated Water Test (proprietary test) with a high concentration of iron oxide.
• Fast and easy maintenance: internal element (control valve and DPCV) can be easily removed, replaced or cleaned.
