An air valve assembly () includes a main housing () including a coupling flange () for coupling to a pipe, and an air valve () fluidly coupled to the main housing (). An actuator () is in fluid communication with the air valve () and a discharge tube (). A non-contact liquid level sensor () is located in an external housing coupled to the main housing (). The non-contact liquid level sensor () is in operative communication with the actuator ().

Air valve with external liquid level sensor

A coupler assembly includes a fluid fitting formed with a first bore at one end thereof and a second bore at an opposite end thereof, both of the bores being formed with female threads. A fluid adaptor includes a neck portion ending in a terminal portion larger in diameter than the neck portion. A fitting ring secures the fluid adaptor to the fitting. The fitting ring includes a split ring that fits over the terminal portion. The fitting ring is formed with a male thread, which mates with the female thread of the second bore of the fitting. The fitting ring has a first inner portion with a flat annular shape and a second inner portion with a curved annular shape.

Coupler assembly that compensates for misalignment

A valve assembly includes a valve installed in a fluid/liquid supply line, and a water circulation pipe that has a first end in fluid communication with a water supply line and a second end in fluid communication with an inner volume of the valve. Some water flowing in the water supply line is diverted through the water circulation pipe and circulates in the valve. The water that is diverted through the water circulation pipe and circulates in the valve has a sufficient flow to prevent freezing and/or water stagnation in the valve.
