BSKN-12/D & BAKN-12/D

Wheel & Key operated small Acetylene valves for “B” & “MC” style cylinders
These are key operated O-ring seal design valves with two-piece stem construction in CGA 520 & CGA 200 outlet respectively. The operating mechanism is similar to wheel operated valves except for change in material of upper stem (SS-303 in place of brass and PEEK soft seat in place of PVDF), to allow the valves to withstand high torques which may be imparted using an external key.
