Mechanical Demand Operated Drain Valves

Reliable and economical, mechanical demand operated drain valves do not waste any valuable compressed air.

Reliable and economical, mechanical 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, mechanical demand operated drains do not require electricity to operate.
