PN 816-1, the air operated toggle valve, is obsolete. It has been replaced by the 816-3 which allows for greater control with lower control pressure. We still stock parts and replacements for the 816-1 but we strongly encourage new designs to use the 816-3. The 816-3 has a larger control piston but if space allows can be used as a replacement for the 816-1 in older designs as well.
