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.
