upplementary Product Intro for Single-Plate Check Valve

TIANYU Single-Plate Check Valve adopts eccentric single-disc spring-driven design, manufactured under strict API and ASME specifications and exported globally to over 60 countries. The Cr13 hardfaced sealing disc paired with precision-machined valve body realizes bubble-tight shutoff conforming to API 598 standard, effectively blocking medium backflow and reducing pipeline water hammer impact. Wafer-style compact structure shortens overall valve length for space-saving installation on compact piping layout, while optional PTFE soft seal variant fits low-temperature clean fluid service and metal hard seal suits high-temperature steam, hydrocarbon and abrasive medium working conditions. Raw materials ranging from cast carbon steel, stainless steel to bronze and titanium enable flexible matching for seawater desalination, petrochemical, thermal power, municipal water treatment and marine engineering sectors. All finished valves pass hydrostatic shell test and helium air tightness inspection before delivery, with average practical service lifespan exceeding 8 years under standard operating environment.

Excelling in Harsh Conditions, Leading the Industry with High-Performance Valves for Stable Operation

Tianyu Valve’s high-performance valves are widely used in harsh operating conditions across industries such as petrochemicals, power generation, metallurgy, and sewage treatment. They excel in scenarios involving high temperature and pressure, strong corrosion, high-velocity fluid erosion, and frequent opening and closing, ensuring stable equipment operation and meeting the unique requirements of various industries.

Single-Plate Check 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.
