Bettis GVO-C Series Pneumatic Linear Valve Actuator

Bettis

A linear pneumatic valve actuator designed for service in safety shutdown and control applications.

Features

  • Full stainless steel construction and standard carbon-fiber material for light-weight durability and low friction (steel, stainless steel, aluminum and brass optional)
  • Suitable in very dirty environments; scale build up on the piston rod will not affect the cylinder performance
  • Conventional linkage arms have been replaced with a fully-enclosed transducer, which is a major design innovation
  • May be fitted with jackscrew or hydraulic pump type manual override
  • Springs are pre-compressed and sealed in a factory-installed canister: no extended tie-rods required, hence, shorter delivery lead time
  • Modular factory seal-welded spring canister for increased safety (no need for extended tie-rods) and modular canister also provides application flexibility and spring thrust availability up to 75,000 lbs
  • Infinite resolution, accuracy to 0.5 percent repeatability
  • Allows remote mounting of positioners (ideal for harsh environment or hazardous areas)
