< )r, an overview
: r, Honeywell automatic exhaust valve uses the force of the float to rise and fall with the liquid level to link the opening and closing of the exhaust device to achieve the purpose of automatic exhaust. When the gas is collected into the valve body, due to the effect of air pressure, the liquid level in the valve body moves downwards, and the float drops accordingly. When it drops to the lower limit, the lever system is linked to open the exhaust valve port and release the pressurized gas. As a result, the valve When the internal pressure decreases, the liquid level moves upward, the float rises, and the exhaust port closes under the action of the spring force. In this way, the gas is continuously collected and discharged, collected and discharged again, completing the automatic exhaust process of pipelines and equipment systems.

: Excellent sealing performance, the sealing ring gasket is made of durable High-temperature synthetic rubber completely eliminates the trouble of water leakage.
: Large exhaust volume: The exhaust volume is proportional to the system pressure.
: Easy maintenance: directly unscrew the valve body for cleaning without affecting the normal operation of the system.
: )Four Application Scope
: Various occasions where gas-water separation is required, such as radiator pipes in heating systems and boiler air-conditioning systems.

, , : ) Six installation Precautions for use
: First install the blocking valve vertically on the pipeline, and then use a wrench to screw the valve body on top of the blocking valve. The above maintenance space should be reserved vertically above the valve body.
: If you need to install it on a /-inch diameter pipe, you only need to add a /-inch to /-inch filler.
: If it does not exhaust, please unscrew the valve body, remove the dirt and reinstall it.
> : Note: The accessory blocking valve is / inch, made of brass, with a diameter of / inch.
