Technical Specifications & Operating Limits
- Maximum Supply Pressure: 150 psi (10.3 bar) standard operating limit for the associated actuator cylinder
- Standard Temperature Rating: -40°F to 350°F (-40°C to 177°C) for standard nitrile/elastomeric components
- Dynamic / Static Application: Formulated for low-friction dynamic piston travel and high-pressure static casing seals
Kit Contents & Components
This Soft Goods Maintenance Kit contains all elastomeric, low-friction, and sealing components required for a standard top-and-bottom cylinder overhaul:
- Piston O-Ring: High-integrity dynamic elastomeric seal for the main piston head
- Cylinder O-Rings: Static sealing rings for the upper and lower cylinder cap interfaces
- Piston Stem O-Rings & Quad-Rings: Primary seals for pressure retention along the linear shaft
- Actuator Stem Wiper: Excludes external dirt, dust, and process moisture from entering the internal cylinder chamber
- Stem Guide Bushings / Bearings: Low-friction wear strips to minimize lateral stem deflection and prevent metallic contact
Design Features
- Zero Lost Motion: Engineered to maintain maximum positioning stiffness and high-thrust output with minimal hysteresis
- Reduced Inventory Costs: Uses standard sizing configurations to service multiple stroke variations within the size 100 frame
- Field Serviceability: Enables fast inline teardown and rebuilding of the pneumatic cylinder without removing the yoke from the control valve body
