The operating principle of the AVENTICS air vent valve is as follows: When water begins to be injected into the pipe, the plug remains in the open position to vent a large amount of air. When all the air is vented, water accumulates in the valve, the float is lifted, and the plug is moved to the closed position, stopping the large-scale venting. When water is being transported normally in the pipe, if a small amount of air accumulates in the valve to a certain extent, the water level in the valve drops, and the float drops accordingly. At this time, the air is discharged through the small hole. When the pump stops, the water in the pipe runs dry, or negative pressure is generated in the pipe, the plug opens quickly to draw in air and ensure the pipeline is secure.

AVENTICS series quick-exhaust valves are pneumatic quick-exhaust valves, with a main body made of aluminum or polymer. They can increase the exhaust speed of cylinders, clutches, or other pneumatic devices. A sensitive, large internal air passage allows for rapid exhaust, accelerating operation, and a special diaphragm prevents valve vibration.
AVENTICS exhaust valves are used for venting pipes in independent heating systems, district heating systems, boilers, central air conditioning, underfloor heating, and solar heating systems. Because water usually contains dissolved air, and the solubility of air decreases as temperature increases, gas gradually separates from the water during circulation, gradually accumulating to form large bubbles or even gas columns. Due to the replenishment of water, gas is frequently generated.
AVENTICS air vents are auxiliary components in piping systems, widely used in boilers, oil and gas pipelines, and water supply and drainage pipes. They are often installed at high points or bends to remove excess gas from the pipes, improve pipeline efficiency, and reduce energy consumption. During the operation of HVAC systems, the gases released when water is heated (such as hydrogen and oxygen) have numerous adverse effects that can damage the system and reduce thermal efficiency. If these gases are not removed in time, many adverse consequences will occur, such as: corrosion due to oxidation; formation of air pockets in radiators; poor or unbalanced hot water circulation, causing some radiators to be unheated; noise from pipes operating with air; and cavitation in circulating pumps.
AVENTICS Air Vent Valve Applications
AVENTICS air vent valves are installed at pump outlets or in water supply and distribution pipelines to remove large quantities of air accumulated in the pipes, or to release small amounts of air accumulated at higher points in the pipeline into the atmosphere. This improves the efficiency of the pipeline and pumps. Furthermore, in the event of negative pressure in the pipeline, this valve quickly draws in outside air to protect the pipeline from damage caused by negative pressure.
AVENTICS Air Vent Valve Working Principle
In the venting state, the float, due to gravity, pulls one end of the lever downwards. At this time, the lever is tilted, creating a gap between the lever and the vent hole. Air is then released through this gap. As air is released, the water level rises, and the float rises under the buoyancy of the water. The sealing end face on the lever gradually presses against the vent hole until the entire vent hole is blocked. The air vent valve is then in the closed state.
Advantages of AVENTICS air release valves:
1. The float of the air release valve is made of low-density PP material, which will not deform even after prolonged immersion in high-temperature water. This prevents difficulty in float movement.
2. The float lever is made of rigid plastic, and the connections between the lever, float, and support are all movable connections. Therefore, it will not rust during long-term operation, preventing system malfunction and leakage.
3. The sealing end of the lever is spring-supported, allowing it to expand and contract with the lever's movement, ensuring a tight seal when no air is released.
Installation: It is best to install the air release valve together with the isolation valve. This ensures a tight system seal and prevents water leakage when the air release valve needs to be removed for maintenance. The low-density PP material will not deform even after prolonged immersion in high-temperature water.
Micro-air venting valve
Under normal circumstances, water contains approximately 2% dissolved air. During water transportation, this air is continuously released from the water and accumulates at high points in the pipeline, forming air pockets that hinder water transportation. This can reduce the system's water delivery capacity by approximately 5-15%. The main function of this micro-air venting valve is to remove this 2% dissolved air. It is suitable for installation in high-rise buildings, industrial piping systems, and small pumping stations to protect or improve system water delivery efficiency and save energy.
The single-lever (SIMPLELEVERTYPE) micro-vent valve has an oval-shaped body. All internal parts, including the float, lever, support, and seat, are made of 304S stainless steel. It uses a standard 1/16" vent orifice and is suitable for operating pressures up to PN25.
Main Specifications:
Nominal Diameter: DN15-DN25
Nominal Pressure: PN10 PN16 PN25
Compound Vent Valve
This valve has a cylindrical body and primarily contains a stainless steel ball, float, and poppet. Installed at the pump outlet or in water supply pipelines, it effectively removes large amounts of air accumulated in the pipes or releases small amounts of air accumulated at higher points in the pipeline into the atmosphere, improving the efficiency of the pipeline and pump. Furthermore, in the event of negative pressure in the pipeline, this valve quickly draws in outside air to protect the pipeline from damage caused by negative pressure.
