Supply DY30AX slow opening slow closing check valve low water loss

DY30AX slow opening slow closing check valve low water loss Brand: Gold Titanium Valve Model: DY30AX Nominal Diameter: DN50 ~ DN600 Nominal pressure: 1.0Mpa, 1.6Mpa, 2.5Mpa, 4.0Mpa Suitable medium: water, oil applicable Temperature: 0 ~ 80 ℃ Connection: Flange material: cast iron, cast steel, ductile iron, stainless steel DY30AX slow opening slow closing check valve low water loss Introduction DY30AX multifunctional pump control valve installed in the general level of the pump outlet, have hydraulic automatic control, when the pump slow opening, when the pump stops after the first slow closing fast closing features, and both the pump outlet water hammer arrester, globe valves, check valves three functions, is a new two-phase closed valve. Multifunctional pump control valve according to the purpose, function and different places can be turned into hydraulic control valve, floating remote control valve, pressure reducing valve, flow control valves, relief valve closed, pressure relief valve, hydraulic electric control valve. DY30AX slow opening slow closing check valve product features low water damage hydraulic control valve is a pressure control valve is composed of a main valve and attached to the catheter, pilot valve, needle valve, ball valve and pressure and so on. Depending on the purpose, function and different places evolved into a hydraulic control valve, floating remote control valve, pressure reducing valve, flow control valves, relief valve closed, pressure relief valve, hydraulic electric control valve. Hydraulic control valve is divided into two types of diaphragm or piston, work on the same principle, are more downstream pressure difference △ P as a driving force, so that the diaphragm (piston) hydraulic differential operation, fully automatic adjustment of the water, so that the main valve When the tray is fully opened or closed in regulation, when entering the diaphragm (piston) in the control room on the cavity pressure water is discharged to the atmosphere and downstream lower region, the role of the pressure of the valve disc on the bottom or below the diaphragm value is greater than the pressure at the top, so the promote fully open valve disc open position when entering the diaphragm chamber (piston) control room pressure water can not be discharged to the atmosphere or lower downstream region, the role of the diaphragm (piston) above the pressure is greater than the pressure below the main valve so it will pan down to the fully closed position, when the diaphragm (piston) pressure in the control room on the cavity inlet and outlet pressure of the intermediate pressure, the main valve disc is in regulation, which adjust the position of the needle depends on the duct and the adjustable guide Joint control valve action. You can adjust the position of the pilot valve is adjustable through the downstream outlet pressure and it changes with open or closed by its own small orifice, thereby changing the diaphragm (piston) pressure in the upper chamber, and control the main valve disc.
