Description
Ductile iron pressure independent control valve offering full authority and automatic balancing function, PN16.
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.
