| Feature | Lift Type (ZHMIL-D1) | Swing Type Check |
|---|---|---|
| Maintenance Cycle | Extended (Simple Structure) | Standard |
| Sealing Reliability | Higher for low-leakage water | General Purpose |
| Flow Resistance | Slightly Higher | Lower |
| Installation Range | Horizontal Only | Horizontal & Vertical |
| Long-term Cost | Lower (Less Part Replacement) | Moderate |
No, lift check valves must be installed on horizontal pipelines to ensure the disc operates correctly via gravity and flow pressure.
They are available in Cast Iron (CI), Ductile Iron (DI), Carbon Steel (WCB), and various Stainless Steel (SS) grades to suit different chemical compatibilities.
The lift check valve disc moves vertically and is typically used for tighter sealing in horizontal lines, while the swing check disc pivots and is more versatile for installation angles.
It is widely used in petroleum, chemical production, water purification equipment, and steam condensate recovery systems.
Yes, it is rated for PN10 and PN16 standards, making it suitable for a wide range of industrial pressure requirements.
The metal-to-metal seat provides superior durability and heat resistance, allowing a very small amount of controlled leakage suitable for specific backflow prevention needs.
