Belimo R3015-P63-P63-B2 - 6-way ball valve with control orifice

Belimo R3015-P63-P63-B2

The 6-way control ball valve with control orifice handles two sequences, e.g. cooling and heating, using a single 90° rotary actuator. It is designed for stationary heating, ventilation and air conditioning systems with a closed water circuit.

Key features and specifications

• DN 15; Rp 1/2" female thread; PN 16.
• Kvs (sequence I): 0.63 m³/h; Kvs (sequence II): 0.63 m³/h.
• Fluid: water, water with max. 50% vol. glycol; fluid 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).
• Nickel-plated brass body; stainless steel control orifice.

The valve has an integrated pressure relief regulator that compensates for changes in fluid pressure in a closed volume. This function is active in the closed position (45°).

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