Blanking pressure sleeve for Badestnost P40 and Z50 manifolds. Screwed in the N hole, it allows to maintain a constant pressure in the hydraulic system by blocking the free flow of oil through the directional control valve to the return line. It changes the hydraulic scheme of the manifold adapting it to operate in closed systems with constant pressure.

The sleeve does not change in any way the mode of operation of the working units such as cylinders or motors, nor does it change the way the individual sections in the manifold are controlled.

It goes to port N to on valve , is perfect solution when you want to change valve from open to closed center lo
