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 beenreplaced with a fully-enclosed transducer, which is a major design innovation
- May befitted 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)
