NQ5001 Thermostatic Control Valve – Manual Temperature Regulation Valve for Radiators

The Coliter® NQ5001 Thermostatic Control Valve is a manually operated thermostatic valve designed for precise temperature control in hydronic radiator heating systems without requiring electricity. It features a user-friendly manual knob with numbered settings (typically 1–5) to adjust heat output based on room comfort preferences. Constructed from high-quality lead-free brass, the valve is rated for a nominal pressure of 1.6 MPa and operates within a medium temperature range of 5°C to 90°C. It complies with ISO 228 (BSP parallel) threading standards and is available in size De15 (G1/2"), with overall dimensions L=80 mm, H=115 mm, and A=41 mm. The valve includes an M30×1.5 mm thread on the actuator head, allowing optional upgrade to an automatic thermostatic head for smart climate control. Ideal for cost-effective, maintenance-free comfort in residential and light commercial buildings.
