This Pneumatic Wafer Butterfly Valve (Standard Model: D671X Soft Seal, D673H Hard Seal) is a general-purpose industrial pipeline control valve with pneumatic automatic actuation as the core and ultra-thin wafer type valve body as the structural basis. Driven by the pneumatic actuator, the disc rotates 90° to quickly realize pipeline on-off and flow proportional regulation.

The Stainless Steel Pneumatic Butterfly Valve is a highly versatile and efficient flow control device, designed to provide optimal performance in corrosive environments. Constructed from stainless steel, this valve ensures superior corrosion resistance, making it suitable for handling aggressive media such as acids, alkalis, seawater, and other harsh chemicals. Equipped with a pneumatic actuator, the valve offers rapid and reliable automated operation, supporting both on/off and modulating control. Its compact and lightweight design ensures easy installation and integration into industrial systems, particularly where space is limited.

This Stainless Steel Lug Type Hard Seal Butterfly Valve is an industrial-grade special valve for harsh working conditions, with integral cast lug structure as the installation core, triple offset metal hard seal as the sealing body, and full stainless steel material as the pressure bearing foundation, which is an upgraded version of ordinary soft seal butterfly valve. The valve body is equipped with positioning lugs with internal threaded holes at both ends, which can realize independent disassembly and maintenance of single-side pipeline without full-line shutdown and emptying.

This Full Lug Type Hard Seal Butterfly Valve is an upgraded version of standard wafer and semi-lug butterfly valves. It features an integrated full lug body with 1:1 flange hole matching, each hole with both through hole and internal thread design, enabling single-side pipeline maintenance without full line shutdown, as well as single-end blind line pressure bearing and dead-end service installation.

This High Performance Wafer Butterfly Valve (Standard Model: D372H Double Offset, D373H Triple Offset) is an industrial-grade pipeline control valve built for high temperature and high pressure harsh conditions. It features a core double/triple offset friction-free metal hard seal structure with a compact wafer type body, boasting low operating torque, long service life, bidirectional zero leakage, high pressure and high temperature resistance.

This Pneumatic High Performance Butterfly Valve (Standard Model: D672X Double Offset, D673H Triple Offset) is an industrial-grade valve for harsh working conditions, with pneumatic intelligent actuation as the control core and double/triple offset friction-free metal hard seal as the high-performance main body.

This Electric Three Eccentric Butterfly Valve (Standard Model: D943H Flanged, D973H Wafer) is an industrial-grade valve for harsh working conditions, with intelligent electric actuation as the control core and 3D triple offset metal hard seal as the high-performance main body. The core adopts 3D triple offset design (shaft eccentricity, disc eccentricity, sealing cone eccentricity), realizing full-stroke friction-free and low-torque operation.

The Triple Eccentric Metal Seat Butterfly Valve is a high-performance valve designed for demanding industrial applications where reliable sealing, high temperature, and high-pressure resistance are required. Its unique triple eccentric structure ensures zero leakage and minimal wear, making it ideal for critical systems in industries such as petrochemical, power generation, metallurgy, and municipal utilities.

The Bi-Directional Metal Sealed Butterfly Valve is a high-performance valve designed for reliable flow control in both flow directions. Unlike conventional unidirectional butterfly valves, this valve utilizes a robust metal sealing structure to ensure effective sealing under bi-directional flow conditions. It is ideal for demanding industrial applications that require high-pressure, high-temperature, and severe environmental resistance. The valve's advanced design, including a precision-engineered metal seal ring and eccentric sealing mechanism, ensures durability and long service life, even under challenging working conditions.

The Butt Weld Metal Seated Butterfly Valve is engineered to provide superior performance in demanding industrial applications. Its butt-weld connection delivers a leak-proof and secure integration into pipelines, while the metal-seated design ensures durability in high-pressure and high-temperature environments. This valve is widely used in applications requiring exceptional reliability, such as petrochemical plants, power generation facilities, and metallurgical processes.

The metal-to-metal hard seal butterfly valve is a high-performance industrial valve designed for demanding applications, featuring a pure metallic sealing pair for exceptional resistance to high temperatures, high pressures, and abrasive media. Suitable for industries such as petrochemical, power generation, metallurgy, and thermal systems, this valve ensures durability and efficiency in extreme operating conditions.

The Pneumatic Hard Seal Butterfly Valve is a high-performance valve designed for reliable operation in demanding industrial applications. It combines a robust metal-sealing structure with the precision and convenience of pneumatic actuation, making it ideal for applications requiring high-temperature and high-pressure resistance, along with tight shutoff capabilities.
