PICV – Pressure independent balancing valve

Area of use

PICV is a control valve with balancing function and differential pressure control in cooling, heating and domestic water systems.
It can be used in a wide variety of sectors: heating, air conditioning, and generally with any non corrosive liquid.

Description

PICV is a pressure independent balancing valve with following features:

  • Easy required flow rate selection using presetting dial
  • Automatic balancing in the event of fluctuating pressure conditions in system  branches
  • Flow rate modulation along the whole actuator stroke
  • Flexibility if the system is modified after the first installation
  • Reduction of balancing costs, improved energy saving and high environmental comfort
  • It is supplied with external thread.

Preset

Take the plastic cap screwed on the upper part of the valve off. Turn the presetting dial device and match the mark on the swivel part with the value stated on the fixed part of said device (1,2,3 etc.) which shall correspond to required flow rate. Do not exceed the working setting range (1-5).
The relation between flow rate and values shown on the presetting dial device are given by the tables stated on the product sheet.
Using the differential manometer Cim 726, check that the differential pressure is higher or the same as the minimum. The differential manometer interfaces with the balancing valve through the two binder points of the valve. When balancing is achieved, screw the lock for presetting dial completely, preventing any unintentional rotation.

PICV is suitable for variable volume system to control fan coil flow rate directly.
