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.

Application

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.
