Cast Steel Bellows Gate Valve:WCB Bonnet,Flanged End,150LB-600LB

ANSI cast steel bellows gate valve:
Design standards: API1600, API6D
Structure length: ASME B16.10 structure
Flange connection: ASME B16.5
Test and inspection: API598, API6D

- Reasonable structure, reliable sealing, excellent performance as well as attractive appearance.
- Sealing surface builds up welding Co base hard alloy,providing a good performance of wear-resisting, anticorrosive and anti-friction.
- Double sealing renders performance more reliable.
- More intuitive indicator for the lifting position of valve rod.
- Materials of parts and the sizes of flanges and butt ends can be reasonably matched to meet the needs of various engineerings according to the actual working conditions or user's requirements
