Description

Brass Threaded on off Pressure Independent Control Valve (PICV) is a new product used for FCU temperature control as well as radiators in heating system. It combines the functions of hydraulic balancing and electrical on/off control in one unit. It features high accurate control, stable operation and compact design.

The PICV is combined with an electrical thermostatic actuator and a two-way balancing control valve, widely used for FCUs in HVAC system and other systems with similar requirement of zone control.

Specification of Valve

◆ Size: DN15, DN20, DN25.

◆ Pressure rating: PN16.

◆ Flow control accuracy: 5%.

◆ Shut off differential pressure: 2.5 bar.

◆ Body material: Brass.

◆ Pressure regulator (orifice): stainless steel.

◆ Disc: EPDM.

◆ Spring: Stainless steel.

◆ Seal Ring: EPDM.

◆ Fluid: water.

◆ Working temperature: 0~95℃

Specification of Actuator

◆ Power Supply: 24VAC, 110VAC, 220~240VAC.

◆ Power input: 3W

◆ Positioning force: 110N

◆ Stroke: 3.5mm

◆ Full Stroke Time: 6min

◆ Connection: M30×1.5mm female thread.

◆ Ambient Temperature: -5~60

◆ Wire length: 900mm

◆ Casing Material: Fire resistant plastic PC

◆ Protection Grade: IP54.

◆ In a water heating system, PICVs shall be installed on the water return branches of the collector, or installed with the thermostatic valve body. The valve shuts off when the actuator is power off.

◆ French PTC heating paraffin wax pusher is used in the actuator.

◆ When power off, the valve shuts off automatically by spring return function.

◆ No noise during working.

◆ Valve opening indicator on the actuator.

◆ Easy and quick fixing by nut connection of actuator.

Functions

◆ Electrical on off control: Open or close the valve based on control signal from room thermostat.

◆ Dynamic balancing control: when the PICV opens, it maintains constant water flow within the allowed pressure range, not impacted by the system pressure fluctuation, automatically obtain hydraulic balance of the water system.
