Key Challenges

The Canadian manufacturing client faced multiple engineering challenges that required support from Juliang Valve Group:

·             Sealing instability: Existing valves failed under vibration and pressure fluctuation, causing leakage in HVAC cleaning cycles.

·             Weight and volume constraints: Traditional valve structures increased total system weight, limiting portability.

·             High procurement cost: Existing supply chain valves increased BOM cost and reduced product competitiveness.

These challenges required a customized engineering response from Juliang Valve Group.

Solution

To address these issues, Juliang Valve Group developed a fully optimized micro solenoid valve solution with three engineering improvements:

·             Zero-leak sealing system: Juliang Valve Group redesigned internal spool geometry and sealing interfaces to eliminate micro-leakage under dynamic pressure conditions.

·             Miniaturized structure design: The engineering team at Juliang Valve Group reduced valve volume and weight to meet portable device requirements.

·             Cost-efficient OEM manufacturing: Juliang Valve Group optimized material selection and production processes to reduce total system cost while maintaining industrial-grade reliability.

Technical Solution

Implementation

The implementation of the Juliang Valve Group Manufacturing solution followed a structured engineering workflow:

·             Prototype valves were developed by Juliang Valve Group and integrated into the client’s HVAC cleaning system.

·             Performance testing included leakage detection, pressure cycling, and vibration simulation.

·             Field validation confirmed stability under real portable operation scenarios.

·             After approval, Juliang Valve Group initiated mass production with strict quality control standards.

·             The original valve supplier was fully replaced by the Juliang Valve Group solution in production.
