101CPS-series Phillips Low Side Float Valves (Adjustable Level - Remote Feed)

The 101 Series valve float ball is linked through a forked lever to act upon a needle or plunger directly over the orifice controlling the refrigerant flow. A spring is installed over the needle, working in opposition to the lever, which supports the weight of the float ball. The spring pressure can be regulated by an external adjusting stem to counteract the weight of the float, causing the liquid level to be lower or higher to any desired point within the range of the spring. Turning the adjusting stem counter-clockwise will raise the liquid level. Total level change, at a particular setting, from a fully closed to a fully open valve is about 2". Unless otherwise stated by the vessel manufacturer, liquid level set point should typically be 2/3 to 3/4 of vessel diameter for flooded ammonia chillers and 40% of vessel diameter for flooded halocarbon chillers. A separating vessel above the chiller is recommended.
