Valve Adaptors, sometimes referred to as "transition plates" or "blocks", fit between valves and subplates or manifolds and allow a customer to mount different size valves on the same manifold, or to replace one size valve on a manifold or subplate with a different size valve.

This module allows for a D03, D05 Alt. A, or D05 Alt. B valve pattern to be adapted onto a D05 Alt. A or Alt. B manifold pattern with pilot ports.
