Description

Expo’s Friction Free Digital Valves (FFD) offer exceptionally low power operation with reliability in a wide range of control system applications. From intermittent use to non-stop cycling, the FFD is fast acting, wear-free, non-sticking and frictionless during operation.

Designed for very long service life, FFDs use modular construction to simplify maintenance and reduce replacement time. A wide range of porting and switching options is available.

The FFD is a direct replacement for Expo's legacy FFV range. Contact Expo with your FFV specification.
