SERIES P VALVES
LAPPED SPOOL VALVES
The heart of the Series P valve is the packless body
and spool assembly constructed of aluminum with
a ceramic hard aluminum oxide finish. This unique
cartridge and spool assembly is completely isolated
from external forces; is pressure balanced, allowing
any port to be pressurized or subjected to back
pressure with no effect on shifting force, and has
been designed to meet the most stringent requirements
that today’s customers demand. All Series
P valves are inline, and all can be manifolded. This
series is manufactured to the highest quality standards
in the industry today and all carry a three year
warranty on all parts of the valve, including the coil.
No lubrication; extremely fast shifting coupled with
very low minimum pilot pressure, a variety of
options and all at a low cost.
CONSTRUCTION:
• Body, End Caps & Manifolds: Anodized
Aluminum
• Cartridge & Spool: Hard Coated Aluminum
• Coils: Molded Nylon
• O-Rings: Buna N (Nitrile)
LUBRICATION:
NONE REQUIRED - However a general purpose
lubricating oil may be used if desired. In these
cases, we recommend ASTM/ISO viscosity Grade
FILTRATION:
A 40 micron filter is recommended.
32.
WARRANTY:
Series P valves are covered by a three year
warranty from date of purchase.Series A & Sprite
are covered by a 90-day warranty. All provisions
of our standard warranty policy (available upon
request) apply.
OPERATING PRESSURES:
• Internal Pilot (Standard): 10 P.S.I. to 150 P.S.I.
• External Pilot: Vacuum to 150 P.S.I.
NOTE: External Pilot Supply of at least 10 P.S.I.
required for vacuum service.
MOUNTING:
All Series P Valves have no limitations as far as
the orientation of the valve. Coils can be rotated
in any direction for ease of installation.
CYCLE RATE:
Series P Valves may be cycled at over 2000
cycles per minute in most applications.
OPTIONS:
Include hard wired coils; factory assembly of
valves to manifolds; a variety of plug connectors;
pre-installed AQ push-in fittings, and many other
popular options.
SERIES A & SPRITE VALVES
Series P Spool Assembly
Alkon Series A and Sprite II valves have been designed to comply with the ever more stringent
requirements for increased production rates through higher speeds and component reliability.
The heart of these valves is a packless spool body and spool assembly constructed of aluminum
with a ceramic hard aluminum oxide finish. Ground and matched to precision tolerances, its operation
is virtually frictionless.
Benefits of this packless design begin with the elimination of dynamic seals and their incumbent
difficulties. Fast response allows increased machine cycle rates; non-lube operation reduces scheduled
maintenance requirements. The body and spool assembly is pressure balanced, allowing any port to
be pressurized or subjected to back pressure with no effect on spool shifting force. Exhaust port
mufflers or speed controls may be used with no effect on valve response.
The unique body and spool assembly has been completely isolated from external forces by use of a
patented 3-point suspension. This assembly, coupled with a complete variety of actuators and
mounting alternatives, provides the highest level of performance and versatility found in the air valve
industry.
