Direct factory supply, wholesale sales, and pricing for electric curved valves. The gate is composed of the main body, sector gate plate, shaft, gears, seals, and actuator. Made of carbon steel welded into unique structure, it operates flexibly and reliably with no jamming. Different transmission devices can meet various operational requirements. Electric gates use electric actuators with overload protection to prevent equipment damage, allowing for remote operation or programmable control with precise positioning and locking. Electro-hydraulic gates use electro-hydraulic actuators with full hydraulic transmission, enabling stepless speed adjustment for both thrust and pull. Pneumatic gates use pneumatic actuators, which can be remotely controlled or locally operated through accessory combinations.
