WALTER Model F8011 Float Control Valve modulates to maintain a constant liquid level in a storage tank by compensating for variations in supply or demand. It can be installed to control the flow into or out of the tank by either closing on a rising level or opening on a rising level. This valve is a hydraulically operated, pilot controlled diaphragm valve.
The pilot control system consists of an integral variable orifice in the main valve cover and a remotely mounted float control. A slight change in liquid level moves the float control. This action varies the pressure in the valve cover, causing the main valve to seek a new position. The integral variable orifice automatically regulates the flow into the cover chamber until the valve reaches a position that is in direct relation to the position of the float control.
Features:
1.Automatic operation, Top and seat ring guided stem and Nylon reinforced diaphragm assembly for long life and reliability.
2.In-line serviceable, Easy maintenance without removal from the main line.
3.Corrosion resistant stainless steel seat and disc retainer ring.
