Forged Steel Lift Check Valves: High-Pressure Non-Return Excellence
A Lift Check Valve is a specialized Non-Return Valve (NRV) where the disc is lifted from the seat by the pressure of the upward fluid. FlowBiz Exports Pvt Ltd manufactures premium Forged Carbon Steel (A105) Lift Check Valves, engineered for high-pressure durability and positive shut-off in critical steam, air, and gas lines.
The FlowBiz Forging Advantage
Unlike cast valves, our Forged Steel A105 bodies undergo a high-pressure forging process that refines the metal's grain structure. This results in:
- Enhanced Safety: Elimination of internal defects like porosity and sand holes.
- Superior Strength: Exceptional resistance to thermal expansion and mechanical stress.
- Zero Leakage: High-density material allows for precision machining of the seat for a bubble-tight seal.
Technical Specifications: ASA 800 Class
Our Lift Check Valves are designed to meet rigorous international standards, ensuring reliability in the most demanding environments.

Rigorous Pressure Testing
Every FlowBiz Forged Valve undergoes stringent hydraulic and pneumatic testing to ensure field performance:
- Body Test (Hydraulic): 207 bar (3003 PSI)
- Seat Test (Hydraulic): 152 bar (2205 PSI)
- Pneumatic Test (Seat): 6.9 bar (100 PSI)
Key Features & Benefits
- One-Way Precision: Ensures fluid flows in only one direction, preventing reverse flow that can damage pumps and compressors.
- Vertical Stability: Lift check valves are ideal for high-velocity services where "slamming" needs to be minimized.
- Ease of Maintenance: The Bolted Cover design allows for quick access to internal components for inspection without removing the valve body from the pipeline.
- Graphite Sealing: High-grade graphite-filled gaskets provide excellent thermal stability and leak prevention.
