Product Description
Butt welded triple offset butterfly valve, This valve is also known as Triple Offset Butterfly Valve. The two offsets are the same as double offsets, and the third one is created by a geometrically designed seat surface. This designed seat and disc create a conical angle, which allows the disc to seal the seat with no friction and come in contact with the shut-off positions. This design in the metal seat provides a bubble-tight shutoff.
Wafer type butterfly valve fits with the help of studs. The studs go through pipe flanges and tighten the valve between two flanges. This type of valve is useful to prevent any backflow in the system. It is designed to keep a seal against bi-directional pressure.
The Lug type butterfly valve also connects in between the flange-ended pipeline. There are threaded inserts on both sides of the valve body. Both sides of the flange-ended pipe connect to these threaded inserts with two sets of bolts without nuts.
Flanged End Butterfly Valve, This type of valve, Valve has a Flanged body that matches the flanged end pipe and fits with the Nut and Bolts.
Butterfly valves are quarter-turn valves that are best used for the stop/start of media flow in pipelines. When the valve handle is turned 90°, it either opens or closes completely. Throttling can be a bit tough, but these valves can still be used for regulating purposes.
Butterfly valves are usually installed in a fully open position. This is because installing the valve in its closed position can cause difficulties with the seat and seal positions.
Butt Welded Butterfly Valves are applied to use in heating system, chemical, petroleum, natural gas, refining, energy, food and the role of regulating valve.
