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.
