medical valve —— High - pressure active valve
High - Pressure Active Valve FAQ (Simplified)
- How does the Pressure Active Valve work?
A: This valve operates via a pressure-activated mechanism to ensure unidirectional flow. When forward pressure meets the system threshold, the valve core actively opens to permit media passage. Upon pressure cessation or reversal, the core instantly reseals through internal structural dynamics, preventing backflow with zero leakage—critical for high-pressure safety and reliability.
- What are its key features?
A:
✅ Extreme Pressure Tolerance: Engineered for high-stress environments, sustaining 2.5 MPa (25 bar) working pressure reliably, far exceeding standard valves.
✅ Backflow Prevention: Automatically seals against reverse flow, eliminating contamination or system failure risks.
✅ Medical-Grade Precision: Specifically designed for high-pressure contrast injection systems (e.g., CT/MRI contrast delivery), meeting stringent medical safety and accuracy standards.
- What are the critical performance parameters?
A: Max Working Pressure: 2.5 MPa, optimized for transient peak pressures in injection cycles.
Response Time: Sub-millisecond closure to counteract pressure fluctuations and prevent backflow.
Media Compatibility: Validated for medical contrast agents and fluids, with biocompatible sealing to ensure patient safety.
- Primary applications and key considerations?
A: Core Application: Exclusively tailored for medical high-pressure contrast injection systems (e.g., CT/MRI imaging), enabling precise, contamination-free contrast delivery without backflow.
