Working Princliple

This kind of valve can be handled both by manual or an electric actuator and also can be operated by a pneumatic actuator.                                                                         
Electirc actuator or penumatic actuator is to covert the axial movement of piston to be 90° rotation of valve shaft.So that the valve can be open or close to achieve the requirement of control and open/close for the pipeline system.They have three type of actuator:normally open(NO),normally closed(NC) ,air/air(A/A).                                                                                                                                                                                                                                     
Multi-position handle regulates the valve by 15° in its open or close 12 seat and achieve control of medium flow purpose.                                                                          
Pulling handle regulates the valve through four multi-function positioning,in its open or close four position and also achieves control of medium flow purpose.
