Pressure Independent Control Valve
PICV Actuators
- Modulating Actuator (ACT1932M)
- The ACT1932M series provides floating and proportional control in HVAC applications. The compact design of this actuator makes it suitable for installation in confined spaces, such as a fan coil, chilled ceiling and manifolds.
-
Due to the innovative concept of auto stroke detection, the ACT1932M automatically calibrates itself to the valve setting, ensuring the control signal is readjusted over the mechanical set stroke setting, providing precise control.
- Configurable analog inputs, configurable direct and reverse action, configurable linear and Eq% controls characteristic and IP43 protection class; make the ACT1932M the best choice for terminal unit applications.
-
Thermal Actuators On/Off (ACT1932TH)
- Natural convection (passive) terminal units, i.e. passive chilled beams and under floor heating, are designed to be less responsive to changes in room temperature than forced convection terminal units.
- Therefore, thermal On-Off actuators should be chosen for natural convection terminal units.
-
On-Off actuators only allow for full flow or no flow
PICV DN15-32
- Maintains equal percentage control characteristic at all flow rate settings
- Pressure independent control of flow
- Simple flow rate setting
- Adjustable over wide range of flow rates
- Compact design
- Integral test points for Dp verification
- Setting key and isolating cap included
- Gap Detection Actuator smart technology, supporting an overall energy efficient HVAC system
PICV Offering Full Authority & Automatic Balancing Function DN50-150
- 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.
