Automatic Timer Drain Valves

Reliable and economical, timer operated drain valves allow regular drainage at pre-determined user selectable time intervals. Designed for use wherever liquids may accumulate in a compressed air system. User selectable open-time and off-time drain intervals allow you to adapt the drain times to meet your specific requirements. Ensures regular drainage will occur at fixed intervals.

Electronic Demand Operated Drain Valves

Reliable and economical, electric demand operated drain valves do not waste any valuable compressed air. They detect the presence of liquid and only operate when filled to a pre-determined level. Upon actuation, they discharge only liquid and close before any compressed air can be exhausted. Fully automatic, they require electricity to operate.
