GKSF pneumatic actuators is specially designed for large torque output. It is a highly unique and reliable means of operating ball, butterfly or plug valves with 90 degree rotating mechanisms.Totally enclosed weatherproof centerbody fabricated in carbon steel or ductile iron provides an excellent strength to weight ratio. for GKSF electric pneumatic actuator torque output can up to 2.000.000 Nm for double acting, even the spring return end (single acting ) the biggest torque outputs is 1.000.000Nm. The output form is hole, and connection size is in conformance with ISO5211 standards, and it also equipped with a hydraulic manual device.
