Belimo R3015-P4-P4-B1 - 6-way control valve

Belimo R3015-P4-P4-B1 – 6-way control valve

Valve with a regulating orifice for switch-over or modulating control of water flow in heating and cooling units in closed-loop water systems. Two sequences are controlled by a single rotary actuator.

Key features and technical data

• DN 15, PN 16; Rp 1/2" female threaded connection.
• Kvs (sequence 1): 0.4 m³/h; Kvs (sequence 2): 0.4 m³/h.
• Medium: water or water with a maximum of 50% vol. glycol; medium temperature 6...80°C [43...176°F].
• Maximum differential pressure ∆pmax 100 kPa; closing pressure ∆ps 350 kPa. For quiet operation: Δpv100 <50 kPa.
• Linear flow characteristic; bubble-tight, leakage rate class A (EN 12266-1).
• 90° rotation angle: sequence 1 over 0...30° (recommended for cooling), dead zone 30...60°, sequence 2 over 60...90° (recommended for heating).
• The integrated function for compensating pressure changes in the enclosed medium operates when the valve is closed (45°), while keeping the two sequences separated.
• Brass body with nickel-plated finish; shut-off element made of chrome-plated brass.

Permitted installation: from vertical to horizontal relative to the spindle. Installation with the spindle pointing downwards is not permitted. Observe the indicated direction of flow.
