Automatic stainless steel exhaust valve that vents trapped air to maintain consistent water pressure and prevent airlocks. Key benefits Prevents airlocks and maintains steady water flow: automatically releases trapped air so pumps and heating circuits run smoothly without frequent manual bleeding. Durable stainless steel construction: resists corrosion for reliable, longterm performance in plumbing systems. Easy integration and secure fit: standardized DN15/DN20 thread sizes ensure a reliable connection with common plumbing fittings for both installations and retrofits. Spacesaving and easy to handle: compact dimensions (7 cm length × 4.8 cm width) fit tight installation spots; lightweight at 114 g for quick, loweffort installation and maintenance. Features Automatic air release action that vents trapped air to preserve consistent pressure and flow. Standardized DN15/DN20 threads for compatibility with a wide range of residential and commercial plumbing components. Compact, lowprofile design suitable for constrained plumbing environments. Stainless steel body for durability in domestic and commercial systems. Typical applications Solar water heater systems: automatically purge air from collectors and lines to improve circulation and efficiency. Domestic hot water and circulation loops: prevent air pockets that reduce flow or cause noise in household plumbing. Commercial water distribution and closedloop systems: maintain reliable flow in small commercial installations where space and accessibility are limited. Notes Designed for integration with standard plumbing fittings using DN15/DN20 threads. Compact size and light weight simplify installation in points or confined spaces where air tends to accumulate.
