The Triple offset (eccentric) design prevents galling and scratches between the metal seat and the metal disc due to its unique design. The only time where the seal comes into contact with the seat is at the point of complete closure. Triple offsset valves are generally used in applications which require bi-directional tight shut-off in oil and gas, LNG/NPG terminal and tanks, chemical factories, and shipbuilding. They are also used for dirty/heavy oil to prevent extrusion.
* Uni-direction
* VOC Gland packing's re-adjusting warning system
* One-piece-stem ( providing maximum strength and stability for high torque applciations. )
* Streamlined disc provide high CV value
* Laminated seat on body ( Increasing seat service life by reducing flow erode. )
* Leakage rate meets API598
* Torque value testing is our stadard procedure in the final stage.
* IP65 Gear operator
* ISO5211 Mounted Pad design for actuation
* Blow-out-proof stem design
Wafer-style buttefly valves The wafer style butterfly valve is designed to maintain a seal agasint bi-directional pressure differential to prevent and backflow in systems designed for unidirectional flow. It accomplishes this with a tightly fitting seal ; i.e. gasket, o-ring, precision machined, and a flat valve face on the upstream and down stream side of the valve.
