Valve body: The main body of a valve, responsible for bearing medium pressure, usually made of high-strength materials such as chrome molybdenum steel, high-pressure stainless steel, etc.

Valve cover: fixed to the valve body, forming the working chamber of the valve and protecting the internal structure.

Valve stem: used to drive the valve disc to move up and down and transmit power.

Valve disc: The core component of a valve that controls the flow of a medium through rotation or lifting.

Sealing ring: Ensure the sealing performance of the valve, prevent medium leakage, and the material needs to withstand medium corrosion and temperature changes. Working Principle:

By rotating the handwheel or activating the actuator, the valve stem can be lifted and lowered to make the valve disc fit or separate from the valve seat:

When closed: the valve disc presses the valve seat tightly, using the medium pressure to enhance the sealing effect;

When opened: The valve disc leaves the valve seat, and fluid flows along the valve body channel. Flow throttling control can be achieved by adjusting the opening of the valve disc.

High pressure shut-off valveCharacteristics:

High pressure adaptability: The valve body adopts a thick wall design with high structural strength, which can withstand high pressure and impact loads.

Excellent sealing performance: The hard seal model is temperature resistant, wear-resistant, and suitable for high temperature and high pressure working conditions; The soft seal model has low sealing leakage and is suitable for clean fluids or low pressure drop scenarios.

Dual function of throttling and cutting off: The conical design of the valve disc and seat has a throttling effect, which can accurately adjust the flow rate. At the same time, it can achieve complete cutting off when closed, avoiding medium leakage.

Corrosion and erosion resistance: Components in contact with the medium are made of corrosion-resistant materials, and special materials such as Hastelloy can be used for highly corrosive media. The valve seat surface is welded with hard alloy to enhance its erosion resistance.
