Description

Our 4100 series features a double disc for redundant bubble tight (optional) shut-off in the event of a seal being damaged, airfoil reinforced disc (optional), an easy replacement of seal on sizes Ø48″ and larger without removing the valve from the line and a positive system isolation in positive or negative pressure systems. Various actuation are available including pneumatic, electric, hydraulic and manual. Each valve is engineered to suit system requirements in configuration, size and face-to-face dimension. The 4100 series can be used with nuclear safety and non-safety related applications for bubble tight shut-off.
