Suitable for high viscosity, suspension, unclean paper pulp, fiber containing medium. Using direct connection is connected with the actuating mechanism, has the advantages of compact structure, small size, light weight, small resistance, stable and reliable. Actuator configured according to user requirements of UNIC, PSQ, HQ, DHL and other types of electronic electric actuator or GTX, AL and other gas actuator Pneumatic piston.
