Comprehensive Center-Line Soft-Sealed Butterfly Valve Solutions

1. Core Design Principles

The center-line soft-sealed butterfly valve operates on a quarter-turn rotational mechanism, where a disc-shaped closure element pivots within the pipeline to regulate flow. Its compact design enables rapid operation while maintaining minimal pressure drop when open. The streamlined flow path reduces turbulence compared to traditional gate valves, and the simplicity of the disc-and-stem assembly ensures reliability across diverse industrial settings.

2. Structural Customization Options

Customization focuses on three key areas

‌Eccentricity Configurations

· Concentric Design: Standard for general-purpose applications.

· Double Eccentric: Reduces wear through shaft offset, ideal for moderate-pressure systems.

· Triple Eccentric: Engineered for high-temperature and high-pressure environments with metal-to-metal sealing.

‌Actuation Systems

· Manual lever operation for cost-effective solutions.

· Pneumatic or electric actuators for automated process control.

‌End Connections

· Wafer-style for space-constrained installations.

· Lugged designs for dead-end service requirements.

· Flanged configurations for high-pressure applications.

3. Industry-Specific Applications

· Oil & Gas‌: Triple-offset designs for sour service compliance.

· ‌Water Treatment‌: Resilient-seated valves for municipal systems.

4. Quality Assurance Framework

Testing Protocols

· Shell tests per API 598 standards.

· Fugitive emission testing for environmental compliance.

‌Documentation

· Material certifications (MTRs) traceable to mill test reports.

· Compliance with PED/ASME pressure vessel directives.

This structured approach ensures butterfly valves deliver optimized performance through precise engineering tailored to operational requirements. Let us tailor the perfect valve for your unique challenges
