Product Features:
·Strong flow capacity, rational construction, small opening/closing torque, hard to jammed.
·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 flange three eccentric butterfly valve.
·The pneumatic actuator must be with positioner to modulate the opening degree of valve.
