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
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.
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.
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℃.
Frequently Asked Questions
Q
What is a rising stem carbon steel gate valve?
A rising stem carbon steel gate valve is an industrial valve whose opening and closing component is a gate plate positioned perpendicular to the fluid direction. As the valve is operated, the stem visibly rises or lowers, indicating the open or closed position. It is available in wedge-shaped or parallel gate plate configurations.
Q
What standards does this gate valve comply with?
This metal seat gate valve is manufactured in compliance with multiple international standards including EN, API, DIN, and GOST, ensuring it meets broad global industrial requirements.
Q
What is the operating temperature range of this gate valve?
The rising stem carbon steel gate valve is designed to operate within a temperature range of -30°C to 425°C, and the WCB gate sluice valve variant is rated for working temperatures from -29°C up to 550°C depending on application requirements.
Q
What industries is the WCB gate sluice valve suitable for?
The WCB gate sluice valve is widely used across petroleum, chemical, hydraulic, and thermal power plant industries. It is applicable to pipelines with nominal pressure ratings from PN1.6 to PN16.0 MPa.
Q
What are the sealing performance specifications of this valve?
The valve features bidirectional sealing with a zero-leakage sealing grade. The sealing surfaces between the disc and valve seat are typically crafted from stainless steel or hard alloy materials, providing highly reliable fluid containment and long-term sealing integrity.
Q
How is this gate valve packaged for export?
All valves are packaged in standard export wooden cases, designed to protect the product against damage during international shipping and handling, ensuring the valve arrives in perfect condition at its destination.
