The valve is designed for variable flow systems and inverter-controlled pumps. It is ideally suited for connecting fan coils, chillers, radiators and other terminal units in buildings with advanced control systems. The linear control characteristic ensures precise and stable temperature control in combination with any Honeywell actuator.

Key features and benefits

• Triple function in a single body – DPCV + flow regulator + 2-way control valve eliminate the need for additional valves and simplify both design and installation.
• Pressure-independent operation – the flow remains constant within a differential pressure range of 30–600 kPa, regardless of network conditions.
• Adjustable maximum flow rate – flow rate presetting in the range of 157–850 l/h is carried out simply using the rotary setting element on the valve body (positions 1–9); no measuring equipment is required.
• Linear control characteristic – in combination with a heat exchanger, it creates a linear control system; it can be converted to an equal percentage characteristic in the actuator.
• Resistance to dirt – the differential pressure regulator is specially designed to withstand microparticles in the medium; tested with an Fe₂O₃ concentration of 900 ppm over 100,000 opening/closing cycles.
• Easy maintenance – the internal cartridge (control valve + DPCV) is removable and can be cleaned without dismantling the pipework.
• Pressure test points – model F (with test points) allows verification of the start-up pressure directly on the valve using a differential pressure gauge.
• EPD certificate – third-party verified Environmental Product Declaration in accordance with ISO 14025 and EN 15804+A2.
• Tested in accordance with BSRIA BTS1/2019 – ensures quality and reliability in line with the industry standard.
