Flow control valves are used to regulate the flow volume of passing fluid in hydraulic systems. It prevents excessive flow by limiting flow to a preselected maximum rate, regardless of changing line pressure. It is a hydraulically operated, pilot controlled, diaphragm valve. The pilot control responds 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 an adjusting screw on the pilot control. SHSUOTE is the top flow conrtrol valve manufacturer in China, hydraulic flow valves provide precision flow control in 1 direction, and automatically allow unrestricted free flow in opposite direction. The valve includes an orifice plate with a holder that should be installed one to five pipe diameters downstream of the Valve.
As a flow control valve supplier, we provide several orifice plate with different hole optional for each size, see the additional table for selection of orifice to guarantee accurate control of flow rate. Contact us for more details!
