D343H hard seal eccentric butterfly valve description:

Flange butterfly valve, mounting between flanges PN10/PN16/A150, with gear box.

The range of WESDOM valves can be used for overground installation, in valve chambers and buried systems.butterfly valves in a range of DN 150 to 2000 mm and PN 10, 16 and 25 bar have been designed to isolate the flow of fluid in:

①Potable water supply pipelines and treatment plants.

②Transportation of filtered and recycled water.

③Irrigation distribution networks.

④Water-pumping stations and hydroelectric plants.

⑤Reservoirs.

The range of WESDOM valves can be used for overground installation, in valve chambers and buried systems. It includes a full range of operating accessories and actuators.

WESDOM valves are installed all over the Asia,Africa continent, the Middle East and throughout Europe. They have justifiably acquired a faultless reputation for their durability, reliability and quality worldwide.

D343H hard seal eccentric butterfly valve characteristic:

①Body adopts integral casting technology, compact structure, small volume and light weight;

②Disc three ccentic mounting. When closed, disc expands outwards to achieve the best peripheral seal; When opened, disc and seal ring quickly separated, effectively prevent the seal ring wear;

③Sealing ring design is novel, simple and maintenance-free;

④Sealing ring form is multi-level metal hard seal,suitable for harsh working conditions;

⑤Due to the use of three eccentric structure, the operating torque is greatly reduced;

⑥The flow resistance is small, the rated flow coefficient is large, about 3 times that of the same caliber single-seat valve;

⑦Strong self-cleaning ability, long service life;

⑧Standard actuators (pneumatic piston and electric) are interchangeable.
