New! ES Series Electronic Valves

The ES Series features large cross sectional o-rings, minimal leak points, and proven poppet designs. To reduce the possibility of contamination, all mounting hardware is outside of the flow path and no internal parts are threaded during assembly. A compact footprint combined with long life and exceptional leak resistance makes this line well-suited to improve reliability in a wide range of applications including biomedical, dental, test equipment, oxygen control, textile, packaging, pressure control, automation, and portable systems.
