2 - 3 Way Diaphragm Valves
Diaphragm valves designed to obtain an optimal fluid passage
with a constant diameter related to their sizes:1/2” 3/4" - 1” -
1"-1/2”.
The diaphragms are in PTFE with seal pad wear recovery. The
valve cannot seize in any situation since it has no seal
gaskets; the reverse movement is very rapid.
The valve life span is over one million reversals, without any
apparent wear. Just think that these diaphragms are mounted as
standard on our compressed air pumps that perform 110-130 cycles
per minute, eight hours a day in continuous operation. In short,
the occasional operation of a valve in this application means
that its duration is practically infinite.
The valves are air piloted with a maximum test bench work
pressure at 8 bar. The optimum pilot pressure should be the same
as the pressure of the fluid being handled, both to save
compressed air and to avoid unnecessary stress on the diaphragm.
The air control is exactly the same as a dual effect cylinder, it enables PLC diagnostics, when there is pressure the valve switching is assured. Even complex circuits can be easily created and are extremely compact thanks to the 3-way flow configuration..

A Typical Application
-
With this configuration, using PLC, a air or manual control can
fully automate the four operations required to feed the ink, recover it, clean the pump,
blades and piping, recover the solvent and restart the cycle.
