Features
- Compact overall structure with small external dimensions and low weight, saving pipeline installation space
- Body and bonnet formed by forging, providing higher plasticity, toughness, and mechanical strength than cast steel equivalents
- Sealing surfaces of disc and seat made from alloy steel or hard alloy butt welding; heat-resistant, corrosion-resistant, and wear-resistant
- Disc opens under downstream media thrust and closes automatically under gravity and back-pressure; action described as sensitive and rapid
- Wide nominal pressure range: CL150 to CL2500 (PN10 to PN420)
- Wide working temperature range: -196 °C to +600 °C
- Multiple end connection options: socket weld, threaded, flanged, butt weld
Notes
- The length of the riveted structure at the threaded end of the socket-welding connection shall comply with the factory standards.
Description
A compact forged steel lift check valve in which the disc opens under downstream media thrust and closes automatically under gravity and back-pressure to prevent reverse flow. Main structural components (body and bonnet) are forged, providing superior mechanical properties compared to cast steel equivalents. Available in a wide range of nominal sizes, pressure classes, and end connection types for use across high-temperature and high-pressure applications.
Available pressure classes
