Characteristics
The rising stem carbon steel gate valve is a widely used industrial valve, with its opening and closing components being gate plates perpendicular to the fluid direction. According to the sealing surface configuration, it can be divided into two types: wedge-shaped gate plate and parallel gate plate.

Advantages
1. Good sealing performance:
The sealing surface between the disc and valve seat is usually made of materials such as stainless steel or hard alloy, which provides reliable sealing and can effectively prevent fluid leakage.
2. Good flow performance:
When fully open, the flow resistance coefficient is extremely small, usually 0.05-0.1. The medium can pass through a straight channel with low pressure loss, making it suitable for high flow transportation.
3. Easy to operate:
The valve stem is exposed, and the position of the gate can be visually seen, making it easy to operate and monitor. Some high-end models will also add scales or color codes on the top of the valve stem, and even be equipped with electronic limit switches to achieve remote valve position monitoring

Packing
Standard export wooden case packaging

Application Scenarios
The WCB gate sluice valve widely applicable to pipelines of various systems in petroleum, chemical, hydraulic, and thermal power plants with nominal pressure PN1.6-PN16.0MPa and working temperature ≤ -29 ℃ -550 ℃.
