The VPE15F15AL model is designed for DN15 connection with a 15 mm female thread and is fitted with a flow cartridge with a maximum set flow rate of 450 l/h. Thanks to its robust construction from dezincification-resistant (DZR) forged brass and a specially shaped differential pressure regulator, the valve operates reliably even in heating or chilled water systems with poorer water quality and microscopic solid particles. The differential pressure regulator is accessible, removable and washable, allowing maintenance to be carried out without shutting down the system.

The valve is suitable for variable flow systems with inverter-controlled pumps, fan coil unit systems, air handling units (AHU) and other HVAC terminal units in commercial and industrial buildings. Flow control accuracy reaches ±10% of the set flow rate or ±5% of the maximum flow rate. The flow rate can be continuously pre-set using the throttling scale with the supplied adjustment key, even while the system is in operation. The valve is compatible with Honeywell M7410, M4100 series actuators and others for both modulating and two-position control.

Main advantages

• Triple integration in a single body: differential pressure regulator + balancing valve + control valve
• Constant flow rate under varying pressure conditions in the system
• Design resistant to medium contamination – reduces the risk of blockage
• Removable and cleanable differential pressure regulator, service without draining
• Adjustable maximum flow rate using the adjustment key, even during operation
• Fully tested by BSRIA, REACH certified
• Body made of dezincification-resistant DZR brass (CuZn36Pb2As)
• Compatible with Honeywell actuators for continuous automation
