Product details

WESDOM double eccentric butterfly valves with tilted disc are designed for easy operation and long service life. The disc seal is made of WESDOM’s drinking water approved EPDM rubber featuring an excellent compression set and ability to regain the original shape. The high quality epoxy coating and fully encapsulated shaft/disc connection ensure optimal corrosion protection and durability.

Double eccentricbutterfly valve Product 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.

Body Test:  1.5 times the working pressure with water. This test is performed after valve assembly and with disc in half position open, it is called as a body hydro test.

Seat Test:  1.1 times the working pressure with water.

Special Test: On request, any other test can be carried out according to special instruction by client.

Product packaging and transportation




The triple eccentric butterfly valve is widely used in metallurgy, electric power, petrochemical, water supply and drainage, and municipal construction and other industrial pipelines with a medium temperature of 425 ℃ or less to adjust the flow rate and load and cut off the fluid.

The maximum pressure rating of the triple eccentric butterfly valve produced by wesdom Valve can reach 2500 pounds, and the standard diameter can reach 120 inches.

The connection mode of the triple eccentric butterfly valve: the clamp, the lug, the flange, the ring connection, the butt welding, the jacket, etc. can be selected, and various structural lengths and standards can be corresponded.

The triple eccentric butterfly valve has a large choice of materials, high and low temperature, and various acids, alkalis and other corrosive media.

Which is widely used in medium temperature under 425°c of metallurgical, power, petrochmical, and municipal construction, drainage and industrial pipe, for regulating traffice and truncated fluid to use.
