VAT 26524-KA21 inline KF16 valve. Normally closed. Many available. I will offer a discount at qty 5+ units. These valves came from a facility that closed down before it was ever run. NO process gas ever touched these units, however they all have handling marks to some degree. See my other listing if you need a position indicator on the valve.
