Scotch Yoke Valve Actuator
Product DescriptionBEIER BR Series most advanced piston pneumatic. The actuator features dual-oriented design Piston with smooth and reliable operation, characterized with large output torque installation and maintenance easily.through the piston ring seal ,air supply pressure acting on the Pistons to move left or right , Runaround, by putting through the fork Section into a rotary motion. Spring reset to realize fail safe piston. Product Features(1)Same size actuator can select a different spring size to realize different output thrust requirements. High stability qualitative spring reset device to ensure spring return force not reduce during the use of force does not vary with the growth of time.(2)Can be adjusted on the stroke limit device adjust range:80°~100°(3)Piston rod using two stem balance guid, effective guarantee stability of the entire piston stroke.(4)Quick disassembly structure, easy maintenance.(5)Soft seal kit to adapt high/low temperature, ensure the sealing performance under different ambient temperatures.(6)Uses the fork structure can withstand high-thrust conversion, Fork section and rotor are made of case hardened.(7)Piston cylinder bore available with Teflon material.
