The Honeywell VPE15F15AV pressure-independent control valve (PICV) from the VPE series is a compact and highly reliable solution for precise flow control in HVAC hydronic systems. In a single body, the valve integrates three functions: a differential pressure control valve (DPCV), a control valve and a two-way control valve. Thanks to this arrangement, it ensures a constant differential pressure across the valve seat, maintaining a stable flow rate regardless of pressure fluctuations in the system. Balancing valves are therefore not required.

The VPE15F15AV model is designed for very low flow rates (19–150 l/h) and is equipped with a 15 mm female thread (Rp 1/2" to EN 10226-1) and pressure test points for differential pressure measurement. The body is made of corrosion-resistant DZR brass (CW602N). The valve is ideal for variable flow systems with inverter-controlled pumps in commercial buildings – offices, hotels, hospitals and industrial facilities.

Key features and benefits

• Three functions integrated in one body – the differential pressure control valve, control valve and two-way control valve eliminate the need for separate system balancing.
• Constant flow regardless of pressure – valve authority close to 1 guarantees precise thermal control even with variable system pressure.
• Resistance to contamination – the differential pressure control valve is specially designed to resist clogging even in the presence of microparticles in the heat transfer fluid.
• Easy maintenance – the internal assemblies (control valve and DPCV) can be removed and cleaned without dismantling the pipework.
• Adjustable maximum flow rate – flow presetting via a graduated adjustment mechanism allows the valve to be adapted to specific design requirements within the range of 19–150 l/h.
• More accurate temperature control – the linear flow characteristic ensures even supply to heat exchangers and improves environmental comfort.
• Compatibility with Honeywell actuators – the valve is fully compatible with M400 and M4100 series thermoelectric actuators as well as ML711CPA, M7410A1001 and other electric actuators (actuators are ordered separately).
• Pressure measurement – the presence of pressure test points makes it possible to verify that the minimum operating pressure has been achieved and to monitor system condition.
• EPD certification – the valve has a verified Environmental Product Declaration in accordance with ISO 14025 and EN 15804+A2.
• Tested to BSRIA BTS1/2019 – performance verified by an independent test laboratory.
