Belimo R3015-P63-P25B1 - 6-way control valve with linear characteristic

Belimo R3015-P63-P25B1 – 6-way control valve

Valve for changeover or modulating water-side flow control in heating and cooling units in closed water systems. The two sequences are operated by a single rotary actuator with a 90° travel range.

Key features and specifications

• DN 15, PN 16; Rp 1/2" female threaded connection according to ISO 7-1.
• Kvs (Sequence 1): 0.63 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; tightness: air-bubble tight, leakage rate A (EN 12266-1).
• Closing pressure ∆ps: 350 kPa; maximum differential pressure ∆pmax: 100 kPa. For low-noise operation: Δpv100 <50 kPa.
• Rotation angle: 90°; Sequence 1: 0...30° (cooling recommended), dead zone: 30...60°, Sequence 2: 60...90° (heating recommended).
• The integrated medium pressure change compensation function is active in the closed position (45°), while keeping the two sequences separate.
• Brass body, nickel-plated finish; closing element made of chrome-plated brass.
• Permitted mounting position: from vertical to horizontal relative to the stem; installation with the stem pointing downwards is not permitted.
