The Honeywell VPE15M15BL valve belongs to the VPE Series PICV (Pressure Independent Control Valve) range – advanced control valves for hydronic heating, cooling and air-handling systems. A single compact body combines three functions: a differential pressure control valve (DPCV), a presetting valve with adjustable maximum flow rate, and a two-way linear control valve. The result is virtually ideal valve authority (≈ 1) and stable flow regardless of the instantaneous pressure conditions in the system.

The VPE15M15BL model is designed for DN15 pipework (G 1/2" M, external thread ISO 228-1), Low Flow category, with a flow range of 42–450 l/h and a differential pressure operating range of 35–600 kPa. The valve is supplied without pressure test points (variant “B” in the designation), as distinct from the version with test points (VPE15F15AL).

Key features and benefits

• Pressure independent: flow remains constant at a differential pressure of 35–600 kPa; variable flow systems with FQ pumps operate without additional hydraulic balancing.
• Adjustable maximum flow rate: presetting in 9 positions (positions 1–9) allows precise limitation of flow to the design value; linear interpolation for intermediate values.
• Linear characteristic: a linear relationship between flow and stroke ensures stable control together with the heat exchanger.
• Resistance to dirt: the differential pressure controller is designed with minimal friction forces between moving parts; the valve was tested over 100,000 cycles in water contaminated with ferric oxide (900 ppm).
• Easy maintenance: the internal assembly (control valve + DPCV) is removable and can be cleaned without removing it from the pipework.
• EPD certification: third-party verified Environmental Product Declaration in accordance with ISO 14025 and EN 15804+A2.
• Actuator compatibility: fully compatible with M400, M800, M4100 series thermoelectric actuators and M6410, M7410, ML711CPA / ML712CPA electric motor actuators.
