1. Pay attention to the flow direction of the medium when installing the valve, and install it strictly in the direction indicated by the flow direction arrow of the valve. 2. The valve can be installed in any position of the pipeline, and the valve of carbon steel or alloy steel can be selected according to the medium and the temperature of the medium. 3. Install it as vertically as possible, with the valve stem u

1. Open and close without friction. This function completely solves the problem that the traditional valve will affect the sealing due to the friction between the sealing surfaces. 2. Top-loading structure. The valve installed on the pipeline can be directly inspected and maintained online, which can effectively reduce the shutdown of the device and reduce the cost. 3. Single valve seat design. It eliminates the pr

The working principle of the electric globe valve is to make the valve unblocked or blocked by rotating the valve. The gate valve switch is light, small in size, can be made into a large diameter, reliable sealing, simple structure, convenient maintenance, sealing surface and spherical surface are often in a closed state, not easy to be eroded by media, and are widely used in various industries. If you w

1.applicability The fluid in the pipeline must be consistent with the medium calibrated in the selected solenoid valve series. The temperature of the fluid must be less than the calibration temperature of the selected solenoid valve. The maximum working pressure difference should be less than the maximum calibration pressure of the solenoid valve; generally, the solenoid valve works in one direction, so pay atte

1. Solenoid valves are divided into three categories in principle: 1) Direct acting solenoid valve: Principle: When energized, the electromagnetic coil generates electromagnetic force to lift the closing member from the valve seat, and the valve opens; when the power is off, the electromagnetic force disappears, the spring presses the closing member on the valve seat, and the valve closes. Features: It can work no
