PCVPQ
Pilot-controlled flow and differential pressurecontroller is a self-acting differential pressurecontroller primarily for use in district heating,district cooling or in industrial systems as well. Itcan be flow and return mounted in applicationswith and without heat exchanger like largesubstations and distribution stations.The control function of the PCVPQ controlleris defined by the control function of the pilotcontroller. Setting of flow is done on maincontroler , setting of differential pressure is doneon the pilot controller.Throttle valve data can be found on page 8.
Features and benefits
- Differential pressure and flow controller
- Extremely high control ratio (see Tab.1) as aresult of low pilot controller min. flow rate(kVS value) and high flow rate (kVS) of the mainvalve
- Small overall dimensions comparing to standard design (especially height)
- Higher valve capacities for DN 150-250comparing to standard design
- High control stability
- Smooth operation flow controller
- Water/glycolic water applications
