Adjustable pusher arms
Two yoke-type arms set the high and low switching points to the span of level you want to control.
Snap-acting float
Micro Valve Level Controller
Two set points define where the controller should start and stop correcting the level. A small pneumatic valve then controls the output between those points.

Overview
Simple control between two level points
Two set points define where the controller should start and stop correcting the level. A small pneumatic valve then controls the output between those points.
The valve is in the low level position when the liquid level is below the float and remains there until the float rises to the pre-set high level. The micro valve then reverses position until the float drops to the pre-set low level. The instrument is supplied with flange and grooved coupling for mounting, from the side of the tank.
Standard instruments are supplied with a three way micro valve and three 1/4" NPT ports; connections to the ports depend on the control action desired.
Three-way micro valve
Three 1/4" NPT ports; the port connections determine the control action.
Oil and condensate duty
Intended for crude oil, oil and condensate service at specific gravity 0.6 to 1.2.
Side mounting
Supplied with flange and grooved coupling for mounting onto the vessel from the side.
