Jump to:
+44 (0)1473 277300 Website

Application

Suitable for use with large plant items such as Air Handling

Units (AHU).

Description

A ductile iron, pressure independent control valve.


Features and benefits:

  • Energy savings: Optimal control creates energy savings when used as part of a variable flow system.
  • Easy to install: For use with large plant items such as Air Handling Units (AHU), the PICV is compact and easy to install in limited and difficult site conditions.
  • Accurate flow rates: Built-in differential pressure controller ensures accurate system design flow rates are achieved and eliminates overflows caused by fluctuating system pressures, which in turn reduces the system running costs.
  • Precise temperature control: Linear or equal percentage characteristics, settable with an actuator, contribute to precise environmental temperature control.
