Our company leverages advanced valve design and manufacturing technology to continuously innovate and introduce new products. Our flagship products, including butterfly valves, gate valve, and check valve, are widely exported to Europe. Among these, butterfly valve products include center butterfly valves, double eccentric butterfly valves, and triple eccentric butterfly valves, designed to meet diverse requirements for pressure, temperature, and medium conditions.
The three types of butterfly valves feature differentiated eccentric structural designs, delivering outstanding performance in terms of sealing performance, operating torque, and service lifespan. They are widely applicable across industries such as municipal engineering, chemicals, power, petroleum, and metallurgy.
I. Center Butterfly Valve (Concentric Butterfly Valve)
Product Features:
The valve shaft, butterfly disc, and valve body are arranged concentrically, ensuring a simple and reliable structure. Features a soft seal seat (e.g., rubber or PTFE), achieving sealing through butterfly disc compression, ensuring “zero leakage” under low-pressure conditions.
Advantages:
Excellent sealing performance, suitable for clean media
Lightweight operation with low opening/closing torque
Cost-effective with low maintenance costs
Limitations:
Limited to lower temperature and pressure ranges
Not suitable for abrasive or corrosive medium
Typical Applications:
Urban water supply and drainage, air conditioning water systems, food and beverage industries, low-pressure gas systems, etc.
II. Double Eccentric Butterfly Valve
Product Features:
Features a double eccentric structure where the valve shaft is offset relative to both the center of the butterfly disc and the center of the valve body sealing surface, significantly reducing friction during opening and closing. Supports both soft seals and metal hard seals.
Advantages:
More lightweight operation with extended service lifespan
Suitable for medium-to-low pressure and medium-temperature conditions, offering greater adaptability
Limitations:
Sealing performance is inferior to triple eccentric structures in high-pressure conditions
Typical Applications:
General chemical media, power plant circulating water, wastewater treatment, and general industrial fluid systems.
III. Triple Eccentric Butterfly Valve
Product Features:
Add a conical angle offset to the valve seat sealing surface based on the double eccentric design, achieving line contact between metal hard seals and truly realizing zero-friction opening and closing. It possesses excellent high-temperature, high-pressure, and corrosion-resistant performance.
Advantages:
Achieves bidirectional zero leakage with reliable sealing
High-temperature and high-pressure resistance, suitable for harsh media
Low operating torque with extremely long service lifespan
Limitations:
Complex structure with higher manufacturing costs
Extremely high requirements for processing and material precision
Typical Applications:
High-temperature steam, oil and gas transportation, acid-alkali media, nuclear power, shipping, and metallurgy in critical applications.
Regardless of your industrial environment, our butterfly valve products offer tailored solutions. From economical center butterfly valves to high-performance triple eccentric butterfly valves, we adhere to stringent quality control standards and reliability testing to ensure long-term stable operation of every valve.
