Series 3 Air-Pilot Operated Valve Cv= .73 - 1.37
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.
