What is an Industrial Gate Valve?
A gate valve is a valve widely used in industrial piping systems that controls the flow of fluid by moving a wedge or parallel gate up and down. The design of the gate valve makes it particularly suitable for full open or full closed operation and not suitable for flow regulation. When the ram is fully raised, fluid can pass through the valve unhindered with little pressure loss. When the gate is lowered to the seat, the flow of fluid is completely blocked. Because of the superior sealing performance of gate valve, it has been widely used in oil, natural gas, water treatment and other fields. Gate valves can be operated by hand wheel or electric actuator for simple and reliable operation, making them ideal for applications where channels need to be kept open or completely closed.
Characteristics of Valve Use
  • Fully open and fully closed design
    Gate valves are designed so that the valve is either
  • Fully open or fully closed
    fully open or fully closed and fluid passes through almost unhindered. This design is 
  • This design is particularly suitable
    This design is particularly suitable for applications where the fluid needs to be completely cut off or opened.
  • Bidirectional seal
    Gate valves usually have good bidirectional seal performance, allowing fluid to pass and maintain a seal from any direction, suitable for bidirectional flow systems.

About The Key Parts of The Gate Valve
  • 01
    Valve Body
    The valve body is the main pressure-bearing component of the gate valve, usually made of cast iron, stainless steel or carbon steel. The valve body design can withstand large working pressures and ensure minimum flow resistance when the fluid passes through.
  • 02
    Valve Gate
    The gate is the core component that controls the flow of fluid, usually in a wedge-shaped or parallel design. During the opening and closing process, a tight seal is formed between the gate and the valve seat to prevent fluid leakage.
  • 03
    Valve Seat
    The valve seat is the sealing surface between the gate and the valve body, usually made of metal material. The precision design of the valve seat ensures a reliable seal when the gate is closed.
  • 04
    Valve Stem
    The valve stem is connected to the gate through a handwheel or actuator to drive the gate up and down to open and close the valve. The valve stem is usually made of high-strength materials to ensure reliable operation under high load conditions.
  • 05
    Operation
    The operation of the gate valve is usually achieved by manual operation or electric actuator. Handwheel control is a common manual method, while electric actuators are used in applications that require remote control or automation.
