A priority flow control takes one pump flow and guarantees a set amount to the priority function first, sending whatever is left over to the secondary circuit. Steering is the classic case: the steering orbital always gets its flow, and the implement gets the remainder.

These are modular sandwich plates. They bolt between the subplate and the directional valve in a Cetop stack, so the priority function is built into the valve assembly rather than plumbed separately — no extra hoses, no extra ports, nothing to leak.

Bolt kits are not included. A modular stack needs longer bolts than a valve mounted straight to the subplate — add one bolt kit per stack, sized for the total stack height.
