UHP system requirements.
Major features of bellows valve offers a long life cycle, excellent purification and minimum particle generation, due to stem support that is located in the outer part, preventing the fiction between the components.
TK-FUJIKIN can provide 4 different types based on the
product configuration,
such as Miniature, Forged, Casting and Y-Type bellows valve.
Low Pressure Manual Bellows Valve - 32A ~ 50A (ABV)
| ■ Cast steel valves suitable for works demanding strength, shock resistance, elongation and heat resistance. ■ The valve seat is designed to produce less dust and gas residue. |
