Parameters:

  • Diameters D= 150mm…800mm
  • Pressure P = 4MPa…16MPa

Installation options:
  • - fastening to the butterfly (spherical) valve body
  • - servomotor is installed onto foundation
  • Servomotor is designed to rotate the valve disk (rotor) when butterfly (spherial) valves are being opened and closed
  • When butterfly (spherial) valves are being closed using counterweight driving mechanism, servomotor acts as a damper at closing

Servomotor features:

  • working fluid - turbine oil
  • adjusting throttling devices provided in servomotors make it possible to set the valve closing time
  • piston packing consists of two pieces: profiled ring made of PTFE and rubber ring as a pretensioning device
