Belimo R3015-1-1P8-B2 - 6-way control valve with orifice

Belimo R3015-1-1P8-B2

6-way control valve with orifice designed to switch or regulate water flow on the heating and cooling element side in closed-loop water systems. Two sequences are operated by one rotary actuator with a 90° range of motion.

Key features and specifications

• DN 15, PN 16; connection: Rp 1/2" female thread.
• Kvs (sequence 1): 1 m³/h; Kvs (sequence 2): 1.8 m³/h.
• Medium: water, water with up to 50% vol. glycol; medium temperature: 6...80°C [43...176°F].
• Differential pressure: ∆pmax 100 kPa; closing pressure: 350 kPa. For quiet operation: Δpv100 <50 kPa.
• Linear flow characteristic; leakage: bubble-tight, leakage class A (EN 12266-1).
• Sequence 1: 0...30° (recommended for cooling); dead zone: 30...60°; sequence 2: 60...90° (recommended for heating).
• Integrated function compensates for pressure changes in the medium trapped in the controlled element; operates when the valve is closed (45°), while keeping the sequences separated.
• Nickel-plated brass body; installation from vertical to horizontal relative to the stem; do not install with the stem pointing downwards.
