Lift Check Valve (Single Flow Valve)

Product Overview: The Lift Check Valve (Single Flow Valve) features a spring-assisted poppet design engineered for automatic, fluid-driven backflow prevention in extreme pressure and high-temperature environments. Built for heavy-duty wellhead applications, this non-return valve provides dependable flow containment across high-pressure mud choke manifolds, Christmas tree injection equipment, and choke lines rated from 2,000 PSI to 15,000 PSI.

Key Features & Advantages:

• Zero Maintenance Design: No lubricated parts required, eliminating the need for routine maintenance and reducing operational downtime.

• Spring-Assisted Poppet Mechanism: Fluid-driven internal poppet ensures positive, rapid sealing to prevent backflow under high flow and differential pressure.

• Flexible Mounting & Connection Options: Available in flanged, clamped, butt-weld, or custom assembled end configurations.

• Severe-Service Compatibility: Fully customizable across all API 6A material grades (AA–HH), product specification levels (PSL1–PSL3), and performance requirement levels (PR1).

• Robust Sealing Architecture: Engineered structural design delivers reliable high-pressure sealing, smooth flow characteristics, and extended service life.
