Coliter®’s differential pressure control valves, led by the YC1001 self-operated model, automatically maintain a constant pressure difference across heating, cooling, or district energy circuits—ensuring stable flow distribution and protecting variable-speed pumps from overload. The YC1001 features a lead-free brass body, adjustable differential pressure range (0.02–0.3 MPa), integrated needle valve for fine-tuning, and optional pressure gauges. Rated at PN16 (1.6 MPa) and suitable for temperatures up to 120°C, it complies with GB/T 22130 standards. Ideal for radiator systems, underfloor heating manifolds, and chiller bypass lines—delivering energy savings, noise reduction, and hydraulic stability without external power or control signals.
