Product Features
Dual Connection Flexibility
QS-G (Threaded): Secure for long-term, fixed equipment.
QS-GF (Flange): Designed for quick maintenance.
Six-lobe Gland for Easy Maintenance
Easy disassembly/assembly with standard tools, reducing downtime.
Bidirectional Flow & Fixed Inner Tube
Fixed inner tube: Minimizes wear for long seal life.
Bidirectional flow: Optimizes media circulation (e.g., heating-cooling), improving energy efficiency.
Precision seals: Auto-compensate for misalignment, providing reliable sealing in vibration.
Material & Performance
Ductile iron: Withstands 220°C/1.8MPa, 100RPM speed. This provides a simple structure, low maintenance, and durability.
FAQ
Q1: How to distinguish QS-G and QS-GF in application scenarios?
A: QS-G (threaded) suits static/low-maintenance equipment (e.g., mixers), with a stable connection reducing leakage. QS-GF (flange) targets high-frequency maintenance devices (e.g., coating rollers), enabling quick disassembly for faster production line response.
Q2: Do these joints require high coaxial accuracy for equipment?
A: The seals feature auto-compensation for minor misalignment (vibration/installation errors); no strict alignment is needed. They provide reliable sealing in complex conditions, compatible with most industrial equipment's standard installation precision.
Summary
QS-G/QS-GF joints combine fixed inner tube, dual connection, and bidirectional flow with a six-lobe gland and ductile iron, ensuring stable, efficient industrial fluid transfer for diverse applications.
