The Coliter® TJ1005 and TJ1015 brass thermostatic radiator valves are precision-engineered for hydronic heating systems, enabling accurate flow regulation to maintain consistent room temperatures. The TJ1005 features a manual adjustable knob for user-controlled heat output, while the TJ1015 is a pre-set fixed-flow valve ideal for system balancing in multi-zone installations. Both models use high-quality brass bodies with nickel plating, operate at PN10 (1.0 MPa), and withstand temperatures up to 110°C. Designed with ISO 228 threads and compatible with standard thermostatic heads, they ensure quiet, reliable performance in residential and commercial underfloor heating or radiator circuits—backed by strict quality control and OEM support.
