PCVPQ
Pilot-controlled flow and differential pressure controller is a self-acting differential pressure controller primarily for use in district heating, district cooling or in industrial systems as well. It can be flow and return mounted in applications with and without heat exchanger like large substations and distribution stations. The control function of the PCVPQ controller is defined by the control function of the pilot controller. Setting of flow is done on main controler , setting of differential pressure is done on 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 a result of low pilot controller min. flow rate (kVS value) and high flow rate (kVS) of the main valve
- Small overall dimensions comparing to standard design (especially height)
- Higher valve capacities for DN 150-250 comparing to standard design
- High control stability
- Smooth operation flow controller
- Water/glycolic water applications
