CAMOZZI Valves - Manual, Mechanical & Air-Pilot

Air-Pilot Valves - Series 3

Series 3 Air-Pilot Operated Valve

Series 3: 1/8" NPTF, 3-way/2-position & 5-way/2-position / 1/4" NPTF, 3-way/2-position, 5-way/2-position, 5-way/3-position, and dual 3-way/2-position valves.

The pneumatically operated,3-way/2-position, 5-way/2-position Series 3 valves have been designed with different methods of return: An Air-Pilot with mechanical spring, Air-Pilot return, or Air-Pilot with bias override 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 valve series 3, two additional holes permit assembly onto the manifold CNVL without the use of a banjo bolt. *See manifold codes at the end of this section.
New versions of this valve have expanded the range to higher flow 1/4" ported valves as well as dual 3-way/2-position valves. 1/8" and 1/4" valves can be mounted on a common manifold by means of a transition plate.
