AVPB, AVPB-F (PN 25)
AVPB (-F) is a self-acting differential pressure controller with flow limitation primarily for use in district heating systems. The controller closes on rising differential pressure or when set max. flow is exceeded.
The controller has a control valve with adjustable flow restrictor, an actuator with one control diaphragm and handle for differential pressure setting (fixed setting version is without handle).
Features and benefits
- Maintains stable differential pressure and limits flow for system protection.
- Adjustable or fixed settings provide flexibility for various applications.
- Suitable for water and glycolic systems up to 150 °C.
