TAC Push Button Valves are miniature pneumatic 2, 3 and 4-way valves available in 10-32 UNF, 1/8 and 1/4 PIPE sizes. All TAC Push Button valves feature an attractive, work hardened SST button "plunger" above a 15/32-32 threaded collar. Button bottoms out on collar to prevent overstroke and valve damage, permitting heavier "strikes" than it's competition. Feature permits panel mounting or acceptance of a variety of TAC Miniature Operators (ordered separately), including a variety of clever specialty air pilot operators.
