A curing press holds pressure and position over long cycle times. The ETK31 version of the 4WRKE16E220L manages that without any pilot line leaving the manifold. It passes 220 l/min nominal flow at up to 350 bar and follows a ±10 V command value.

Applications
The valve serves presses with long holding phases, clamping systems and axes that keep a position for the whole cycle. Because the pilot stage is fed internally, piping stays limited to the main channels. Swapping for a version with an external pilot path calls for a change on the manifold.
