Microvalve Level Controller

Introduction:

This is a snap action float operated level controls, equipped with 3 way MICRO VALVE unit. Actuated by two adjustable York-type pusher arms. Adjustable pusher arms permit the control range to be adjusted easily and accurately to the range desired. With the liquid level is below the float the 3 way micro valve will be in the low level position and will remain there until the float rises to the pre-set high level. The micro valve then will reverse position until the float drops to the pre-set low level position.

Installation & Operation:

This model is equipped with flange/Groova Grooved coupling for mounting on to the vessel from side. The float is designed to pass through a 100mm tank nozzle. This model is equipped with a three way micro valve with three ¼" NPT ports. The micro valve has standard working pressure of 2kg/cm². Connection to the ports depend on the control action desired.
