Multi-Standard Wafer Butterfly Valve



Product Features and Applications
Structural Features
Multi-Standard Design
A multi-standard butterfly valve is designed to comply with multiple international standards, such as ANSI, DIN, JIS, and GB. This allows the valve to be used in various standard piping systems, providing strong versatility and adaptability.
Wafer Connection
With a wafer design, the valve is clamped between two pipe flanges. Installation is simple: just place the valve between the flanges and secure it with bolts. This design is convenient to install and requires minimal space.
Sealing Structure
The valve uses either a soft seal or hard seal structure. Soft seals (such as EPDM or NBR) are suitable for low-temperature and normal pressure environments, while hard seals (such as metal seals) are designed for high-temperature and high-pressure conditions.
Bidirectional Sealing
The valve can effectively seal in both directions of fluid flow, eliminating the need to consider the flow direction, making it more flexible to use.
Compact Structure
The valve’s compact design, lightweight construction, and ease of operation make it particularly suitable for applications where space is limited.
Performance Characteristics
Wide Applicability
The multi-standard design enables the valve to adapt to different international flange standards, making it widely applicable in global markets. This reduces the complexity of engineering design and procurement.
Easy Installation
The wafer connection method makes the installation and removal of the valve extremely simple, reducing installation time and costs. This is particularly advantageous for applications requiring quick construction and maintenance.
Reliable Sealing
Depending on the selected sealing structure, the valve can provide excellent sealing performance in both low-temperature, normal pressure environments and high-temperature, high-pressure conditions, ensuring no leakage of the medium.
Precise Flow Control
By adjusting the opening angle of the disc, precise control of the medium’s flow rate can be achieved, making it particularly suitable for piping systems that require flow regulation.
Easy Operation
Due to its simple structure, the valve is very easy to operate. For manual operation, simply turn the handle to open or close the valve, while valves equipped with actuators can be controlled remotely.
Application Fields
Industrial piping system
Widely used in industrial fields such as petroleum, chemical, metallurgy, and papermaking, it is used to control and regulate the flow of various liquid and gas media.
Water treatment system
In systems such as water supply, sewage treatment, and seawater desalination, it controls the switch and adjustment of water flow to ensure the normal operation of the system.
HVAC system
In HVAC systems, it is used to adjust the flow of hot and cold water to ensure the efficient operation and energy utilization of the system.
Food and pharmaceutical industry:
Butterfly valves made of stainless steel are suitable for food and pharmaceutical production lines with high hygiene requirements to control the transportation of fluids.
