Diaphragm Hydraulic Control Valve

The working principle of a diaphragm type hydraulic control valve is a device that controls flow or pressure by changing the cross-sectional area of the medium flow. Its main components include valve body, valve core, driving device, and control system. During the working process, when the control system sends a signal, the driving device adjusts the valve core to the corresponding position. When the valve core is opened, the medium can smoothly flow through the valve body, achieving flow or pressure regulation. When the valve core is closed, the flow cross-sectional area of the valve body decreases, thereby increasing the flow resistance and limiting the flow rate of the medium, achieving the goal of reducing flow rate or increasing pressure. The diaphragm type hydraulic control valve produced by Shanghai Meiyanyi Pump Valve mainly refers to the sealing between the control chamber and the flow chamber of the control valve, which is isolated by a diaphragm. Like the piston type, the diaphragm type hydraulic control valve is a full range of products, but it is generally only suitable for hydraulic control valves with diameters below DN400 and pressures below PN25. It has high sensitivity and short opening and closing time.
