Safety Exhaust 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 Safety Exhaust Automatic Drain Valves allow the down stream pressure to be released when the valve is in the closed, “off” position.
