FEATURES


  • Actuators Comply to AWWA C541, PED 2014/68/EU, ASME Sec VIII
  • Single Spring and Multi Spring Design makes Supriya Actuators Compact. 
  • Unique design of piston and piston rod engagement allows rotation of piston rod. 
  • Supriya Spring Return Actuators are designed to operate horizontally or vertically. 
  • Versatile Manual Override options are available. 
  • Spring Assembly is designed to provide a Safe and Easy replacement of seals without disturbing the pre-compression of spring.
  • Hydraulic Manual Override - Compact Type assembled within the spring assembly reduces the overall height by 33% 
  • High Pressure Actuators with 14bar operating pressure available on request.
     

BENEFITS


1) Periodic maintenance is easy to perform since the spring return actuator only requires the removal of three-four parts to access all internal parts.
2) A variety of positioner, instrumentation, controller options makes the spring return actuator ideal for a variety of process control applications. 
3) Using standard O-rings and seals for both static and dynamic sealing makes Supriya spring return actuator soft parts lower cost and easier to find.
4) Our highly engineering springs with stronger materials and better surface treatment and finish provides exceptionally long fatigue life.
5) Our actuators are designed for 20years of service life.
