Stainless Steel Check Valve: Durability and Reliable Backflow Prevention
A stainless steel check valve is a type of non-return valve that allows fluid to flow in one direction while preventing backflow. Its construction from stainless steel ensures excellent durability, corrosion resistance, and longevity, even in harsh environments. These valves are commonly used in applications where the prevention of backflow is essential, such as in pipelines for water, gas, and steam.
One of the key advantages of using a stainless steel check valve is its ability to operate automatically without any external control. The valve flap closes due to gravity, ensuring the flow remains unidirectional. This makes it ideal for applications where maintaining pressure and preventing contamination are critical. The rugged construction and precise engineering ensure safety within the appropriate pressure and temperature range.
Our stainless steel check valves are available in various sizes (DN15–DN600) and can handle temperature ranges from -25°C to 450°C. With the option for flange and butt-weld connections, these valves are versatile and easy to install.
Quick Release Air Valve: Efficient Air Release and System Protection
The quick release air valve is essential in any system where air must be quickly released or admitted to prevent vacuum conditions or overpressure. This valve is particularly useful in pipelines and systems where trapped air can cause operational issues, such as pressure surges or pipeline damage.
A quick release air valve operates automatically, releasing air during the filling of pipes and allowing air to enter during negative pressure conditions. This ensures the system remains balanced and protected. The quick release feature is crucial for maintaining the system’s integrity, preventing water hammer, and avoiding costly downtime.
Our quick release air valves are made from high-quality materials, such as ductile iron and stainless steel, ensuring durability and reliability. They are designed to handle pressures up to PN16 and temperatures ranging from 0°C to 90°C. Installation is straightforward, with the valve being mounted at the highest point in the pipeline to ensure optimal air release.
Lug Butterfly Valve: Versatile and Cost-Effective Flow Control
The lug butterfly valve is a type of quarter-turn valve that is widely used for isolating or regulating flow in various systems. Its design is simple yet effective, making it a cost-effective solution for many industrial applications. The lug butterfly valve is particularly favored in water supply, wastewater treatment, and HVAC systems due to its compact size, ease of installation, and low maintenance requirements.
One of the standout features of the lug butterfly valve is its versatility. It can be used for both on/off and throttling applications, providing reliable flow control with minimal pressure drop. The valve’s design allows it to be installed between flanges in pipelines, with the lug pattern enabling it to be used as an end-of-line valve or for dead-end service.
Our lug butterfly valves are available in various sizes (DN50–DN3000) and pressure ratings (PN16), ensuring they can meet a wide range of industrial needs. Made from materials like stainless steel and ductile iron, these valves offer excellent corrosion resistance and long service life.

Butterfly valves are essential components in various industrial applications. Among the most popular types are the lug butterfly valve and wafer-type butterfly valve. These valves are known for their efficient performance and ease of installation. In this article, we will delve into the design of the sealing mechanism of a lug butterfly valve. We will highlight how it ensures leak tightness and why it is a preferred choice for many industries.
Understanding the Lug Butterfly Valve
A lug butterfly valve features threaded inserts, or lugs, on either side of the valve body, enabling it to be installed using two sets of bolts without nuts. This design allows the valve to act as a pipe end when closed, making it possible to disconnect one side of the pipeline without disturbing the other. This feature is particularly beneficial in applications where maintenance or isolation of a section of the pipeline is required.
Sealing Mechanism of Lug Type Butterfly Valve
The sealing mechanism of a lug type butterfly valve is designed to provide a tight seal, preventing leaks and ensuring efficient operation. The key components of this sealing mechanism include:
Valve Disc: The disc, often made of stainless steel or other durable materials, rotates to open or close the valve. The precision in the design of the disc plays a crucial role in ensuring that the valve seals properly when in the closed position.
Seat: The seat is typically made of elastomeric materials such as EPDM, NBR, or PTFE, which provide a flexible yet tight seal against the disc. The material choice for the seat depends on the application and the type of media flowing through the valve.
Sealing Surface: The contact surface between the disc and the seat is meticulously designed to ensure a leak-tight seal. This surface must be smooth and precisely machined to prevent any gaps that could lead to leaks.
O-Rings and Gaskets: Additional sealing elements like O-rings and gaskets are often used in the valve assembly to enhance the overall sealing capability. These components provide secondary seals, ensuring no leakage occurs through the valve body.
Advantages of Lug Type Butterfly Valve
The lug type butterfly valve offers several advantages over other types of valves, making it a preferred choice in many applications:
Isolation Capability: Unlike wafer-type butterfly valves, the lug type valve can isolate sections of the pipeline, making it ideal for maintenance and repair tasks.
Durability: The robust design of the lug butterfly valve ensures long-lasting performance, even in harsh environments. The use of high-quality materials for the disc and seat enhances its durability.
Versatility: This valve type is compatible with various drive options, including pneumatic and electric actuators, allowing for remote operation and automation in industrial systems.
Easy Installation: The threaded inserts on the valve body facilitate easy installation and removal without the need for nuts, reducing the complexity and time required for installation.
Choosing the Right Valve for Your Needs
When selecting a butterfly valve for your application, it’s crucial to consider the specific requirements of your system. The lug type butterfly valve is particularly suitable for applications that require frequent maintenance or isolation of pipeline sections. It is also a preferred choice for end-of-line service, where the valve serves as a pipe end.
