Butterfly Valve Series

A butterfly valve is a quarter-turn rotary motion valve that uses a circular disc mounted on a rotating shaft to control the flow of fluid, offering quick opening and closing, low torque operation, and is commonly applied in water treatment, HVAC systems, and industrial pipelines due to its compact size and cost - effectiveness.

D971X Electric Wafer Type Rubber-seated Butterfly Valve

The D971X Electric Wafer Type Rubber-seated Butterfly Valve has an extremely small operating torque, allowing for convenient and labor-saving operation. It can be flexibly installed in any position, which greatly enhances the flexibility and convenience of installation. In addition, the sealing element can be easily replaced, and its sealing performance is extremely reliable, achieving bi-directional sealing with zero leakage.

D941H Electric Flanged Butterfly Valve

The D941H Electric Hard Sealing Butterfly Valve adopts a precise J-shaped elastic sealing ring and a triple-eccentric multi-layer metal hard sealing structure. It is widely applied to industrial pipeline systems in various fields such as metallurgy, electric power, petrochemical industry, water supply and drainage, and municipal construction, where the medium temperature is no higher than 425℃.

American Standard Butterfly Valve

This high-performance manual butterfly valve features an innovative double-eccentric design and a special oblique-cone elliptical seal. It overcomes the sliding friction issue of traditional eccentric valves during the 0°-10° opening/closing phase, enabling instant seal separation upon opening and tight sealing upon closure. This significantly enhances both sealing performance and service life.

D71F46 Full Fluorine Lined Wafer Butterfly Valve

This is a soft-sealed butterfly valve, suitable for working conditions where the temperature does not exceed 120℃ and the nominal pressure is no more than 1.6 Mpa. In the pipeline systems for water supply, drainage, and gas transportation in industries such as food, pharmaceuticals, chemicals, petroleum, electric power, textile, and paper-making, it can efficiently regulate flow and cut off media, demonstrating excellent adaptability and reliability.

D341F46 Fluorine Lined Butterfly Valve

The D341F46 fluorine-lined flanged butterfly valve features a flanged butt joint structure, with an integrated design for the valve body, valve seat, and valve core lining. During the operation of the valve, only the lining of the valve body and the plastic-lined butterfly disc come into contact with the medium, enabling it to effectively resist corrosion from media that the lining material is suitable for. The valve is equipped with a four-stage sealing structure, and a heat-resistant and anti-aging silicone rubber elastic gasket is installed at the sealing surface, thus achieving zero leakage of the medium.

D343H Bi-directional Triple-eccentric Hard-sealed Butterfly Valve

The metal hard-sealed butterfly valve adopts an advanced triple-eccentric sealing structure, and the sealing ring is made of high-quality stainless steel, offering excellent bi-directional sealing performance. During installation, this valve is not restricted by the flow direction of the medium or spatial position, allowing for installation in any orientation, which greatly enhances installation flexibility. Moreover, its driving device supports multi-position installation (rotatable by 90° or 180°), fully meeting the requirements of various usage scenarios.

D341X Turbine-driven Flanged Rubber Butterfly Valve

The D341X Turbine-driven Flanged Rubber Butterfly Valve, with its unique structural design, combines the advantages of light weight and rapid opening and closing. Featuring an extremely low operating torque, it offers effortless and convenient operation. Installation is unrestricted by spatial position, allowing for flexible installation at any angle, while maintenance is straightforward, fully demonstrating its practical and efficient product features.

XD371X Signal Butterfly Valve

The XD371X Fire Signal Butterfly Valve features a simple and ingenious structural design, boasting excellent sealing performance and allowing for easy and effortless opening. It is widely applied to various pipelines in systems such as water supply and drainage, as well as building fire protection systems. This signal butterfly valve can accurately display the open and closed states of the valve, clearly and intuitively reflecting the working status of the fire protection system.

TD341W Ventilation Butterfly Valve

The TD341W ventilation butterfly valve is meticulously crafted using the steel plate welding process. The specially designed oil-sealed retaining ring on the valve body significantly reduces the risk of leakage. An ample expansion gap is reserved between the butterfly disc and the valve body, effectively preventing the jamming problem caused by thermal expansion and contraction. This valve supports a variety of driving configurations and is widely applied to the pipeline systems in industrial fields such as metallurgy, petrochemical industry, and mining, enabling precise control and flow regulation of the gaseous medium.
