eccentric flanged butterfly valve

Purpose
The butterfly valve is suitable for use in metallurgy, chemical power, municipal engineering and medium such as water, oil and air pipeline, as cutting fluid and adjust medium flow rate, etc.

Features
1.This butterfly valve structure design novelty, overall size is small, light weight.
2.Disc plate with double eccentric, opening and closing is rapid, convenient operation.
3.Disc plate with double eccentric, No sliding friction between disc plate and the sealing ring, sealing surface wear resistance long service life, reliable sealing, easy to adjust

Working principle
Rotate the butterfly valve handwheel, through the worm worm gear transmission, drive the stem disc plate with in the scope of 90 degrees to rotate, the disc plate is in open or closed,achieve the goal of on and off or cut off the medium.
