Coliter®’s exhaust valves automatically vent trapped air from heating, cooling, and water supply pipelines to prevent airlocks, noise, corrosion, and reduced efficiency. The series includes the QB1 single-port flange exhaust valve for main lines, KB1 single-port quick exhaust valve with enhanced discharge speed, and the CARX1.0 compound automatic air release valve that handles both large initial air volumes and micro-bubbles during operation. Constructed from high-quality cast iron or brass with stainless steel float mechanisms, these valves operate at PN16 (1.6 MPa) and temperatures up to 110°C. Ideal for installation at system high points, pump inlets, and manifold tops—ensuring smooth flow, pump protection, and optimal thermal performance in HVAC and plumbing networks.
