Screw for convert valve to Closed center loop For valves P80 Z 80  John Deere ... 3/4''

Blank pressure sleeve, designed for Badestnost P80 and Z80 manifolds. Screwed into the N hole, it allows to maintain constant pressure in the hydraulic system by blocking the free flow of oil through the manifold to the return line. It changes the hydraulic scheme of the manifold adapting it to work in closed systems with constant pressure.

The sleeve does not in any way change the mode of operation of working units such as cylinders or motors, also does not change the way of controlling individual sections in the manifold.

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