Coliter ® Angle Manual Thermostatic Valve – 1.0 MPa, 0–100°C, for Hydronic Radiator Systems

NQ2012 Angle Manual Thermostatic Valve – Brass Temperature Control Valve for Radiators

The Coliter® NQ2012 Angle Manual Thermostatic Valve is a manually operated thermostatic radiator valve designed for reliable, electricity-free temperature regulation in hydronic heating systems. Its angle configuration allows for flexible pipe routing in tight installation spaces while maintaining efficient flow control. The valve features 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 two sizes: DN15 (G1/2") with B=16 mm, L=53 mm, H=90 mm, and DN20 (G3/4") with B=16 mm, L=55 mm, H=95 mm. The valve head includes an M30×1.5 mm thread, enabling optional upgrade to an automatic thermostatic actuator. Ideal for cost-effective, maintenance-free comfort in residential and light commercial buildings.
