Function

To ensure the correct amount of refrigerant is present in cooling system.

Technical

High side floats are vertically orientated, so the needle valve and seat will be completely covered with liquid when the ball is at the lowest oint of travel, and the valve closed. This liquid seal at the valve seat eliminates the erosion of the valve needle and seat due to vapor. A double-seating service inlet valve is mounted at the top of the receiver. This valve is equipped with a purging plug so that any air trapped in the top of the receiver, may be purged off. The receiver inlet is fitted with a fine mesh screen, to prevent dirt from entering the system. The outlet side of the receiver is fitted with a liquid and a shut-off valve mechanism. (ref. 3)
