OverviewARVX stainless steel micro vent valve is a precision automatic valve made of all stainless steel, specially designed to continuously and automatically discharge micro amount of dissolved gas slowly separated out from liquid pipeline system. It does not process a large amount of free air, but automatically opens the tiny exhaust port under the system pressure through the precise ball (or displacer) mechanism to continuously discharge the trace gas accumulated at the high point of the pipe, so as to effectively prevent the formation of air bag, reduce air resistance, optimize the system efficiency, and protect the pump and instrument from cavitation. Its all-stainless steel construction ensures excellent corrosion resistance and hygiene. It is mainly used in closed circulating water system, solar heating system, precision industrial cooling system, food and pharmaceutical process pipeline, HVAC system and high-rise building water supply network and other occasions with high requirements on system efficiency, tightness and material cleanliness. It is usually installed at the local highest point of the system or near the outlet of the heat exchanger and pump, as the key auxiliary equipment to prevent the accumulation of trace gas and ensure the continuous and efficient operation of the system.Product Drawing of ARVX Stainless Steel Trace Exhaust Valve

OverviewQB1 automatic single port exhaust valve is a structurally simplified, economical and practical basic automatic exhaust valve designed specifically for discharging free air accumulated at local high points in liquid pipeline systems. It automatically opens the exhaust through a single exhaust port and a built-in float mechanism when the pipeline is filled with water or gas accumulates, and automatically closes when the water level rises, effectively eliminating small airbags, preventing air resistance, and ensuring smooth system flow. Its design highlights reliability and economy, making it an entry-level preferred solution for solving conventional pipeline gas problems. Mainly used for heating systems (radiator high points), small solar hot water systems, indoor water supply branches, industrial cooling devices and other occasions where pipeline pressure is stable, gas production is not large, and only basic exhaust function is required in buildings. It is a commonly used and effective accessory for solving local air blockages and improving system circulation efficiency. QB1 Automatic Single Port Exhaust Valve Product Diagram

OverviewC30 combined air valve is a multi-functional combined air valve integrating high-speed intake/exhaust valve and trace exhaust valve. It is specially designed for intelligent management of air in the system at different stages such as water filling, operation and emptying of pipes. The valve can quickly discharge a large amount of free air, continuously discharge dissolved gas, and instantaneously suck air when the system generates negative pressure, effectively prevent air resistance, eliminate water hammer, and avoid vacuum deformation of the pipeline. It is the key equipment to ensure safe, efficient and stable operation of the water conveyance system. It is widely used in long-distance water pipeline, high point and fluctuation section of municipal water supply network, main water inlet and outlet pipe of pump station, technical water supply system of hydropower station, main pipeline of industrial circulating water and fire water supply system of large buildings. Through intelligent air management, it effectively solves the three core problems of air resistance, water hammer and vacuum, and is an important guarantee to improve system safety and operation efficiency.C30 Combined Air Valve product diagram

P11X copper external thread exhaust valve is a compact automatic exhaust valve with a brass valve body and external thread interface, designed specifically for discharging free air in liquid pipeline systems. It automatically controls the opening and closing of a single exhaust port through the lifting and lowering of an internal floating ball, with a simple structure and sensitive response. Copper material provides excellent corrosion resistance and thermal conductivity, and the external thread connection makes installation and disassembly extremely convenient. It is an economical and practical accessory for local exhaust and prevention of gas blockage on small-diameter pipelines or equipment. Widely used at the top of heating radiators (radiators), small solar collection systems, electric water heaters, wall mounted boilers, circulation pump outlets, and the highest point of small-diameter pipelines or equipment such as air conditioning chilled water pipelines in homes and commercial buildings. Mainly used for automatically discharging accumulated air, ensuring smooth circulation and stable heat exchange efficiency in small water systems.P11X Copper External Thread Exhaust Valve Product Drawing
