Product Description

Product Description

GATE VALVE

The gate valve is a shutoff valve that controls the flow of pipeline media through the vertical movement of the gate. Its core component is a wedge-shaped or parallel gate, which is driven by the valve stem to move up and down to achieve the full open or full closed state of the valve. This valve design focuses on completely cutting off the flow of the medium, and can provide a straight flow channel in the fully open state to minimize the fluid resistance.

The most prominent feature of the gate valve is its full-diameter design and reliable shutoff performance. When the valve is fully opened, the gate is completely retracted into the upper part of the valve body to form a flow channel consistent with the diameter of the pipeline, and almost no additional flow resistance is generated. Its sealing surface adopts a metal-to-metal or soft sealing structure, which can achieve strict medium isolation in the closed state. This valve structure is sturdy and durable, with low maintenance requirements, and can still maintain good sealing performance when not in operation for a long time.

Gate valves are widely used in various industrial pipeline systems that require a reliable shut-off. It is used as the main shutoff valve in long-distance oil and gas pipelines, used to isolate different process media in chemical plants, and to control water vapor circuits in power station systems. Gate valves are widely used as regional control valves in urban water supply and drainage networks, and ship systems also rely on their reliable shut-off function.

FULL-BORE LOW-RESISTANCE DESIGN

The gate valve adopts a flow channel structure with the same diameter as the pipeline. When opened, the valve plate is completely separated from the medium flow path, forming a nearly unobstructed straight-through flow channel. This design significantly reduces pressure loss and is particularly suitable for large-flow conveying systems, which can maximize the medium flow rate and system energy efficiency.
 

BIDIRECTIONAL SEALING CAPABILITY

Effective sealing can be achieved on both sides of the gate valve plate without being restricted by the flow direction of the medium. The symmetrical sealing structure design ensures the same sealing effect when installed in the forward or reverse direction, providing more flexible options for pipeline layout.

SIMPLE AND DURABLE STRUCTURE

The gate valve consists of fewer moving parts and has a simple and reliable mechanical structure. The lifting stem design avoids rotational wear, so that the valve can still maintain stable operating performance in long-term use, greatly extending the maintenance cycle.

MULTIPLE DRIVE MODE ADAPTATION

Handwheels, gearboxes, and electric or pneumatic actuators can be flexibly configured. The modular design allows the same valve body to be adapted to different drive devices to meet various working conditions from manual operation to automatic control.
 

HIGH ADAPTABILITY

The wedge-shaped gate design can enhance the sealing effect as the system pressure increases. The solid integral casting valve body can withstand higher pipeline pressures and is particularly suitable for high-pressure media cutoff applications in the fields of petroleum and chemical industries.
