Custom Air Valve Solutions

We offer specialized air valve solutions engineered to match your precise operational requirements and environmental conditions, available in a wide range of materials to ensure compatibility with your system.

Material Options: Brass, Stainless Steel, Monel, Hastelloy, Inconel, and other exotic alloys
Configuration Options: Spring-loaded, threaded, quick-connect, and custom designs
Integration Methods: Embedded, surface-mounted, or molded-in valve designs
Environmental Compatibility: Solutions for extreme temperatures, corrosive environments, and high-pressure applications

Application Note

Custom valve selection ensures optimal inflation performance, longevity, and chemical compatibility in your specific operating environment.

Specialized Corner Solutions

Our engineered corner solutions provide reliable sealing at critical junctions while maintaining the integrity and longevity of your inflatable seal system.

Molded Corners: Custom-engineered for sharp radii requirements
Seamless Integration: Continuous sealing performance around complex geometries
Enhanced Durability: Optimized stress distribution for extended service life
Precision Manufacturing: Tight dimensional tolerances for perfect fit

Design Consideration

We specifically avoid 90-degree corners in inflatable seal designs as sharp angles create stress concentration points that significantly reduce seal longevity. Our molded corner solutions incorporate appropriate radii to distribute inflation forces evenly, dramatically improving reliability and service life.

End-Stop Configuration Options

Our versatile end-stop configurations provide controlled termination points for your inflatable seal system, enabling precise integration with existing structures and mechanisms.

Straight Profile End-Stops: Clean termination for linear seal applications
U-Shape Configurations: Specialized solutions for door and hatch applications
Custom Geometries: End-stops engineered for any seal profile or shape
Mounting Options: Various attachment methods for secure integration

Design Flexibility

Our end-stop designs can incorporate air feed-through points, mounting features, and transition elements to ensure perfect integration with your equipment while maintaining optimal seal performance.

Expansion Direction Types

Selecting the right expansion direction for your inflatable seal is crucial for achieving optimal sealing performance in your specific application.

Axial Expansion: Expands perpendicular to the mounting surface, ideal for face sealing applications like door and hatch seals.
Radial Expansion: Expands outward from the center axis, perfect for sealing the inside of tubes, pipes, and cylindrical openings.
Radial Compression: Contracts inward when inflated, ideal for external sealing of shafts and other cylindrical components.
Multi-Directional: Combines multiple expansion directions for complex applications requiring sealing against surfaces at different orientations.

Application-Specific Design

Our engineering team analyzes your specific requirements to recommend the optimal expansion direction, ensuring maximum sealing efficiency and prolonged service life in your operational environment.

Key Design Considerations

Achieving optimal inflatable seal performance requires careful consideration of multiple interdependent factors during the design process.

Operating Environment: Temperature ranges, pressure requirements, chemical exposure, and UV/ozone conditions all impact material selection and design.
Mounting Configuration: Proper mounting integration ensures reliable seal performance while accommodating dimensional tolerances.
Inflation System: Appropriate pressure control systems optimize seal performance and prevent over-inflation damage.
Cycle Life Requirements: Design considerations for applications requiring frequent inflation/deflation versus sustained long-term inflation.

Engineering Precision

Our engineering team employs advanced simulation tools including Finite Element Analysis to predict seal behavior under various operating conditions, ensuring optimal performance before production begins.
