TIANYU High-performance gate valves

The gate valve is a multi-turn valve that is installed in the pipeline as an isolation valve for full open and close service.
The valve is operated by a threaded stem forcing the gate to the two seats and blocking the fluid. The seats are normally metal with hard facing(stellite CoCrW or SS Overlay) to ensure a long working life. It can also be a soft seat for specified services like water.
Gate valves are widely used for all types of applications and are suitable for various fluids such as water, oil, steam, gas, and slurry.

Why Choose TianYu Industrial Gate Valves?

Our valves feature excellent casting quality, with every Bosseal casting inspected to MSS SP-55 standards, strictly controlling defects like gas porosity, cracks, and shrinkage. The flexible wedge design compensates for seat distortion and body deformation, offering long working life—seat surfaces provide ample wear travel and optional CoCrA hard facing. A straight, standard bore ensures low flow resistance at full opening, maximizing fluid passage. Easy, lockable operation comes from reasonable gland nut torque, long-thread stems, and durable stem nuts, while handwheels/gears include lockable structures for secure handling.

Gate Valve Parts

Sealing Element

The sealing element is vital for valves, preventing media leakage when closed. Made of durable, corrosion-resistant materials, it withstands pressure, temperature, and corrosion. Its repeated friction during operation makes material choice and manufacturing quality crucial for sealing performance and valve lifespan, regardless of valve type.

Valve Stem

The valve stem links the closure element to the operating mechanism, controlling its movement to regulate media flow. It requires strength and rigidity to withstand forces while maintaining stability. Its design and quality directly impact the valve’s flexibility and durability.

Valve Body

The valve body serves as the core structure of the valve, forming the main framework that provides installation and support for other components. It houses the internal channels for media flow. Whether it’s a ball valve, butterfly valve, or gate valve, the valve body is the most essential part, directly influencing the valve’s performance, flow characteristics, and service life.

Valve Cover

The valve cover is the enclosed part of the valve, typically connected to the valve body to form a sealed space within the valve. Its main function is to protect the internal components of the valve from external impurities and ensure complete sealing when the valve is closed, preventing media leakage. The design and manufacturing quality of the valve cover significantly impact the overall performance of the valve.
