ABSTRACT:
Liquid level control apparatus consisting of a valve frame with supply gas throughput through an adjustable orifice post and a float actuated release of orifice post pressure to cause a sharp change in pressure to actuate a pressure-responsive dump valve. Proposed then is the further interconnection of the valve frame in reversed disposition to a snap action pilot valve thereby to provide a non-bleeding mode of valve control.
