Model GIG/GIGS Direct Gas

  • Description
  • Specifications
  • Documentation

Double Acting and Spring Return Direct Gas Quarter-turn Actuators Output Torques to 6,500,000 lb.in.

Features & Benefits:

  • Separate gas and hydraulic cylinders prevent commingling of gas and oil, eliminating any possibility of oil release to the atmosphere during the opening or closing cycle.
  • Scotch yoke mechanism generates high break torque for the actuation of quarter-turn pipeline valves.
  • Totally enclosed, weatherproof carbon steel housing protects the critical internal components against corrosive elements.
  • Heavily chrome plated guide bar provides support for the transverse forces generated during rotation of the scotch yoke, ensuring proper support of the piston rod and valve stem.
  • All load-bearing components supplied with bronze or PTFE-graphite-bronze bearings, eliminating the need for lubrication maintenance and ensuring durable, smooth operation.
  • Electroless nickel plated cylinder wall provides a smooth, long lasting sealing surface for the piston seal, assuring maximum sealing integrity and long service life.
  • ISO 9001 certified design and manufacturing process provides assurance of a quality finished product.
  • Integral manual hand pump provides a means of cycling the valve when sufficient line pressure is not available.
  • Power gas consumption is significantly reduced as there are no gas/hydraulic tanks incorporated in the design.
  • Independently adjustable ‘open’ and ‘close’ travel stops are located on center with the piston rod thus eliminating sideloading to the output shaft.
  • Internationally recognized ISO 5211 mounting patterns facilitate in-field interchangeability of adaption hardware.
