    What is an electric knife gate valve?

    The electric knife gate valve is an electric control valve with a compact structure, easy operation, and high reliability, mainly composed of an electric motor, reducer, knife plate and valve body, and other components. Its working principle is to control the rotation of the motor through the electric controller and drive the reducer to drive the knife plate in the valve body to switch on and off to achieve the purpose of controlling the flow of media in the pipeline.

    The main features of the electric knife gate valve are as follows:

    1. Good regulating performance:
    The electric knife gate valve has precise regulating performance and can realize accurate flow control.

    2. Compact structure:
    Because of the combination structure of the electric motor and reducer, the electric knife gate valve is small in size and compact in structure, which can be applied to some pipeline systems with limited space.

    3. Convenient operation:
    The electric knife gate valve adopts electric drive mode, which is convenient to operate and can realize remote control and automatic control.

    4. High reliability:
    The use of high-quality valve materials can ensure the reliability and durability of the electric knife gate valve in the process of use.

    5. Wide applicability:
    The electric knife gate valve can be applied to all kinds of media, such as steam, gas, liquid, and other media control.

    Quality control process

    quality control process

    Standard Test

    Body Test: 1.5 times the working pressure with water. This test is performed after valve assembly and with disc in half position open, it is called as a body hydro test.

    Seat Test: 1.1 times the working pressure with water.

    Function / Operation Test: At the time of final inspection, each valve and its actuator (Flow-Control Lever / Gear / Pneumatic Actuator), under goes a complete operating test (Open/Close). This test carried out without pressure and at ambient temperature. It ensures the correct operation of the valve / actuator assembly with accessories such as solenoid valve, limit switches, air filter regulator etc.

    Special Test: On request, any other test can be carried out according to special instruction by client.
