Product Details

Product Features:

·Small size, light weight, and rational construction.

·Good performance for anti-corrosion, anti-high temperature and anti-abrasion.

·Good mechanical performance and sealing performance can achieve zero leakage.。

·Using BGT　Series quarter turn pneumatic actuator,　it can be used to control small size wafer three eccentric butterfly valve.

·The pneumatic actuator must be with positioner to modulate the opening degree of valve.
