Belimo R3015-P25-P25B2 - 6-way linear-characteristic control valve

Belimo R3015-P25-P25B2 – 6-way valve

Linear-characteristic control valve designed for switching or modulating water-side control of heating and cooling units in closed water systems. Both sequences are operated by a single rotary actuator with a 90° rotation angle.

Key features and specifications

• DN 15, PN 16; female Rp 1/2" connection compliant with ISO 7-1.
• Kvs (Sequence 1): 0.25 m³/h; Kvs (Sequence 2): 0.25 m³/h.
• Medium: water or water with glycol up to max. 50% by volume; medium temperature 6...80°C [43...176°F].
• Flow characteristic: linear. Bubble-tight, leakage rate class A (EN 12266-1).
• Position ranges: Sequence 1: 0...30° (cooling recommended); dead zone: 30...60°; Sequence 2: 60...90° (heating recommended).
• Integrated pressure compensation for changes in trapped medium, active when the valve is at 45°; separation of both sequences is maintained.
• Closing pressure ∆ps: 350 kPa; maximum differential pressure ∆pmax: 100 kPa.
• Nickel-plated brass body; closing element made of chrome-plated brass.

Permitted mounting position: from vertical to horizontal in relation to the stem. Mounting with the stem pointing downwards is not permitted.
