Belimo R3015-P25-P25-B1 - 6-way characterised control ball valve

Belimo R3015-P25-P25-B1 – 6-way valve

The characterised control ball valve serves two sequences, cooling and heating, using a single 90° rotary actuator. It is designed for stationary heating, ventilation and air-conditioning systems and closed-loop water systems.

Key features and parameters

• DN 15; connection: Rp 1/2" female thread according to ISO 7-1; PN 16.
• Kvs (sequence I): 0.25 m³/h; Kvs (sequence II): 0.25 m³/h.
• Medium: water, water with up to 50% vol. glycol; medium temperature: 6...80°C [43...176°F].
• Maximum differential pressure ∆pmax: 100 kPa; closing pressure ∆ps: 350 kPa; quiet operation Δpv100 <50 kPa.
• Flow characteristic: linear; permissible leakage: bubble-tight, leakage rate A (EN 12266-1).
• Angle of rotation: 90°; sequence 1: 0...30° (cooling recommended), dead zone: 30...60°, sequence 2: 60...90° (heating recommended).
• Valve body: nickel-plated brass; closing element: chrome-plated brass; regulating orifice: brass.

The valve has an integrated pressure reducer that compensates for changes in medium pressure in a closed volume. This function operates in the closed position (45°).

Permitted installation: from vertical to horizontal relative to the spindle. Do not install with the axis pointing downwards.
