WALTER Brand F8040 Flow Control Valve prevents excessive flow by limiting flow to a preselected MAX. rate, regardless of changing line pressure, diaphragm valve. The pilot control response to the differential pressure produced across an orifice plate installed downstream of the valve. Accurate control is assured as very small changes in the controlling differential pressure produce immediate corrective action of the main valve. Flow rate adjustments are made by turning and adjusting screw on the pilot.
The valve includes an orifice plate with a holder the should be installed one to five pipe diameters downstream of the valve. To guarantee accurate control of flow rate, there are several orifice plate with different hold optional for each size.

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.
4.Various pilots and accessories available for configuration into many different applications.
5.Special V-Port is options, please consult factory.

Quick Detail

1, Flow Control Valve, Flow Rate Control Valve, Automatic Control Valve
2, F8040 Flow Control Valve is hydraulically operated automatic control valve that limits the flow to a pre-set value, regardless of pressure variations. In case of flow rate lower than the required set point the valve will be fully opened.
3,F8040, DN50-DN600, PN10, PN16, PN25

Applications

1.Flow rate control at the supply line of a tank.
2.Pumps protection against excessive flow conditions.
3.Avoiding excessive flow if installed on gravity lines right downstream of storage tanks.
4.Stabilizing water consumption of secondary lines and districts in derivation from main and elevated pressure zones.
