Automatic fast venting for quieter, more efficient systems Automatically expels trapped air from hydronic systems, maintaining optimal circulation and heat transfer without manual adjustment. Reduces flow noise and prevents air-related performance loss so pumps and radiators run more quietly and efficiently. Reliable temperature and pressure performance Rated for operation up to 100 C and capable of withstanding 16 Bar (6 MPa), ensuring dependable service in demanding heating applications. Durable brass construction and attractive finish Precision-machined brass body for corrosion resistance and long service life. Gold-colored finish adds a tidy, professional appearance to visible installations. Why you need this valve Prevents trapped-air problems that cause uneven heating, noisy pipes, and increased energy use. Works automatically so you don’t need to bleed radiators manually or stop the system for maintenance. Built to withstand high operating conditions common in residential and commercial hydronic systems. Key features at a glance Function: Automatic air vent for removal of residual air. Material: Brass construction with gold finish. Performance: Up to 100 C and 16 Bar (6 MPa). Maintenance: Minimal; automatic operation removes need for frequent manual bleeding. Practical applications Central heating systems and radiator installations to remove air pockets and improve heat distribution. Boiler and circulator lines to protect pumps from cavitation and maintain system efficiency. Hydronic loops in light commercial or residential installations where automatic air elimination and robust pressure ratings are required. Installation and use notes Designed to be fitted into typical hydronic plumbing locations where air accumulates (radiator tops, high points, boiler runouts). Automatic operation eliminates the need for routine manual venting; periodic visual inspection recommended. What this product solves Eliminates noisy, inefficient operation caused by trapped air. Reduces maintenance time and helps preserve system performance and component life. Provides a durable, professional-looking solution compatible with common heating system environments.
