Automatic Drain Valves
Automatic Drain Valves are an important safety feature for compressed air applications
with downstream pneumatic equipment.
A conventional shut off valve can trap compressed air in pneumatic equipment, which could create a potentially
dangerous situation. Lance Automatic Drain Valves allow the down stream pressure to be released when the valve
is in the closed, “off” position.
