NQ2039 Angle Manual Thermostatic Valve – Brass Temperature Control Valve for Radiators

The Coliter® NQ2039 Angle Manual Thermostatic Valve is a manually operated thermostatic radiator valve designed for simple, reliable temperature regulation in hydronic heating systems—without electricity. Featuring an angle configuration, it allows flexible pipe routing while maintaining optimal flow control. The valve includes a manual knob with numbered settings (typically 1–5) to adjust heat output based on user preference. Constructed from high-quality lead-free brass, it is rated for a nominal pressure of 1.0 MPa and suitable for water temperatures from 0°C to 100°C. It complies with ISO 228 (BSP parallel) threading standards and is available in size 20×20 mm (G3/4"), with dimensions L=53.5 mm, H1=53 mm, H2=42 mm. The valve features an M30×1.5 mm thread on the head, enabling optional upgrade to an automatic thermostatic actuator. Ideal for cost-effective, maintenance-free comfort in residential and light commercial buildings.
