CAMOZZI Valves - Manual, Mechanical & Air-Pilot

Air-Pilot Valves - Series 4

Series 4 Air-Pilot Operated Valve

Series 4: 1/8", 1/4" NPTF, 3-way/2-position; 5-way/2-position; 5-way/3-position
1/2" NPTF 5-way/2-position

The pneumatically operated,3-way/2-position, 5-way/2-position Series 4 valves have been designed with different methods of return: an Air-Pilot with mechanical spring, Air-Pilot return, or Air-Pilot with bias return. This is possible due to the type of design consisting of a balanced spool, which means that it can be used for a very wide range of applications. (including reverse porting)

The 3-way/2-position valves are normally closed in the rest position when the pressure is supplied at P, and are normally open when the pressure is supplied at R, the use of A remaining unchanged.
Moreover, the 5-way/2-position valves can be supplied via the ports R and S with two different pressures if a cylinder must be operated using a delivery pressure different from the return pressure.

On the Series 4 valves, two additional holes permit assembly onto the manifold CNVL without the use
of a banjo bolt. * See pages at end of sections for manifold options.

Key - Series 4 valves incorporate a double lip (Z) seal against the spool. This seal design has improved wear and sealing properties against the spool and spacer glands for when the fluid media is less than optimal.

Key - Series 4 valves incorporate a more robust packed bore design than the Series 3 valves. This
supports the improved (Z) seal design and better wear life of the seals.
