FEATURES


Supriya Prototech
  • Actuators Comply to AWWA C541, PED 2014/68/EU, ASME Sec VIII
  • Actuators are suitable for SIL-3 environments. 
  • Supriya Scotch Yoke Actuators are highly efficient and interchangeable modular design providing easy field modification, operational flexibility and serviceability. 
  • Actuators are designed to maintain product consistency throughout any project requirements, regardless of valve size, pressure class, actuator supply medium and functional requirements. 
  • Scotch Yoke Mechanism is designed to achieve powerful opening and closing torque outputs, and to eliminate piston rod deflection (due to side loads) effectively. 
  • Namur VDI/VDE 3845 mounting options available on all sizes. Provision to mount solenoid valves, limit switches, positioners and other controllers is available. 
  • Each Scotch Yoke Actuator is engineered to bidirectional travel stops with adjustable travel range of 80° to 100°. 
  • Symmetric Yoke and Canted Yoke design provides flexibility to achieve cost effective solution by critically sizing the actuator.
     

DESIGN FEATURES


1. The actuator can easily be converted to fail open from fail close, by interchanging the spring and pneumatic modules.
2. Single Spring and Multi Spring Design makes Supriya Actuators Compact.
3. Spring Assembly is designed to provide a Safe and Easy replacement of seals without disturbing the pre-compression of spring.
4. High Pressure Actuators with 14bar operating pressure available on request.
5. Safety comes first - springs are assembled in cartridge and sealed to avoid any possible mishandling.
6. Our highly engineering springs with stronger materials and better surface treatment and finish provides exceptionally long fatigue life.
7. Hydraulic Manual Override - Compact Type assembled within the spring assembly reduces the overall height by 33%.
8. Our actuators are designed for 20years of service life.
