A floating ball valve is a valve in which the ball can float. Under the action of medium pressure, t...
The Lift Check Valve is a type of non-return valve where the disc lifts vertically with forward flow and seats firmly when flow stops or reverses. Its piston-like movement and guided alignment make it ideal for high-pressure, high-velocity, and clean fluid systems, ensuring tight shut-off and long service life. Commonly used in steam, gas, oil, and water pipelines, it excels in vertical upward flows and applications that require compact, efficient sealing.
Who Uses Lift Check Valves?
| User | User Profile | Key Priorities |
| Power Plant Engineer | Oversees high-pressure steam or condensate systems | Tight Shut-Off, High Temp Resistance |
| Chemical Process Engineer | Manages clean, pressurized pipelines | Precise Sealing, Long Wear Life |
| Pump System Designer | Works with vertical discharge pipelines | Reliable Vertical Functionality |
| Industrial Maintenance Supervisor | Handles valve inspection cycles | Easy Access, Replaceable Seat & Disc |
Key Features & Benefits:
Disc Lifts Vertically on Flow
Automatically drops into place when flow stops—ideal for upward vertical or horizontal lines.
Guided Disc Alignment
Ensures smooth movement, reduces turbulence and uneven wear.
Tight Metal-to-Metal Sealing
Excellent for steam and high-temperature applications.
Compact Body Design
Takes up less space than swing-type valves in piping layouts.
Optional Soft Seated Designs
Available for air, water, or corrosive media to reduce noise and improve sealing.
