Belimo R3025-6P3-6P3B3 - 6-way control valve with flow characteristic

Belimo R3025-6P3-6P3B3 – 6-way control valve

Designed for switching or modulating water-side control of heating and cooling units in closed water systems. It is operated by a rotary actuator with a 90° rotation angle.

Key features and specifications

• DN 25, PN 16; Rp 1" female-thread connection according to ISO 7-1.
• Kvs (Sequence 1): 6.3 m³/h; Kvs (Sequence 2): 6.3 m³/h.
• Medium: water or water with up to 50% vol. glycol; medium temperature: 6...80°C [43...176°F].
• Linear flow characteristic; bubble-tight, leakage rate class A (EN 12266-1).
• Closing pressure ∆ps: 350 kPa; maximum differential pressure ∆pmax: 100 kPa. For low-noise operation: Δpv100 <50 kPa.
• Rotation ranges: Sequence 1: 0...30° (cooling recommended); dead zone: 30...60°; Sequence 2: 60...90° (heating recommended).
• The integrated function compensating for changes in medium pressure is active when the valve is closed (45°), while keeping the two sequences separated.
• Nickel-plated brass body; chrome-plated brass closing element.
• Permissible mounting position: from vertical to horizontal relative to the stem; installation with the stem pointing downwards is not permitted.
