Series P Valves

Lapped Spool Valves

Alkon Lapped Spool Valve
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 in-line, 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.


A 40micron filter is recommended.

Series P-4-Way Valves

Manifolds can be purchased separately or valves can be assembled to them at the factory.
Hardened mounting pins (2) are screwed into the valve body (5) until flush, and then the valve unit is inserted into the manifold block (4) after positioning the O-rings (1). By tightening the Allen head screws (3), the valves are seated and connected to the manifold block. This unique method assures a leak proof assembly. When manifolds are purchased separately, each kit contains mounting pins, set screws and O-rings for the purchased number of stations.

Series A Valves

Sprite Valve Actuator

Alkon Sprite Valve Actuator & Air PilotSPRITE solenoid/pilot operators are available for single or double actuation applications in horizontal configurations.
The SPRITE actuator offers lapped spool reliability in both valve and operator, providing a maintenance-free product life measured in multi-millions of cycles currently unobtainable from standard pilot/solenoid operators.
Offered in a wide variety of voltages and frequencies; all coils are rated for continuous or maintained signal service and continuous repeatable cycle rates in excess of 3000 CPM are possible. Molded coils are standard and solenoid housings meet most JIC and NEMA IV criteria. Non-locking manual override is standard.

Air Pilot

Alkon AIR BLEEDER OPERATEDIn applications where electrical controls are not suitable, or where they are hazardous, air pilot operated valves can be used. These valves can also be applied for special purpose circuitry such as sequencing or timing operations. Since the low friction characteristics of the body and spool assembly requires only .50 psig to shift, vacuum can be considered as a signal source. Air pilot operated valves, do however require external valves to supply the required signal pressure.

Alkon AIR BLEEDER OPERATEDAir Bleeder Operated

Both air pilot and bleeder operated valves can be applied when electrical control is impractical or hazardous. The bleeder can be used in place of the air pilot model where limited space prohibits the external pilot pressure supply required by the external pilot control valves.
Bleeder Operators
#6000, Plunger type bleeder operator is used when striking force is straight on. #8492, Ball type bleeder operator has a hardened ball for cam actuation.

Manual & Mechanically Operated Valves

Alkon Manually & mechanically Operated ValvesAvailable with either hand, foot or palm button actuators, manually operated Series A valves can be used directly as power valves to control air actuators or indirectly to operate larger pilot operated hydraulic or pneumatic valves. Hand or foot operated models are available with spring offset or with optional two position detent.
Three position, spring centered or detented, open or closed center hand valves are available as special assemblies. Consult factory.
Actuating force of palm button is only 2 lbs.

Multiple Station Manifolds

Alkon Multiple Station ManifoldsSeries A valves may be manifold mounted in a flexible arrangement which allows the stacking of any number of valves in any combination of actuators. With multiple manifold assembly, only one inlet connection is required for the entire manifold assembly.
The exhaust port on the manifold is also common to all valves in the assembly. Both inlet and exhaust ports are 1/2 NPT. Cylinder ports are available in either 1/4 or 3/8 NPT. All manifold bases are provided with side and bottom cylinder ports and are shipped with the bottom cylinder ports plugged unless otherwise specified.

Sprite Valves

Alkon Sprite Valves3 & 4-Way Air Valves That Bring a New Concept to Air Valve Design
The SPRITE II is truly a unique miniature solenoid air valve. It brings a technology to pneumatic control that through the years has proven on-the-job reliability in the small electrical relay field. This proven technology of solenoid actuation, and Alkon’s time tested lapped spool valve elements combine as the basis of the exciting SPRITE II valve.
The SPRITE II valve has been specifically designed to bring a higher level of reliability to pneumatic equipment, and at the same time a new level of versatility to system design.

Omni 250 Series Valves

Alkon Omni 250 Series ValvesAir Pilot Operated
The OMNI Series 3-Way and 4-Way valves can be air pilot operated with three types of assemblies:

  • Double Air Pilot (No Valve Spool Spring) The valve spool is shifted by a momentary air pilot signal to either of the “A” or “B” Pilots.
  • Single Air Pilot, Spring Return The valve spool is maintained in the normal rest position in the “B” end. A maintained air pressure signal at the “A” end greater than the spring force will shift the valve spool.
  • Double Air Pilot, Spring Offset The valve spool is maintained in the normal rest position in the “B” end. A maintained air pressure signal at the “A” end greater than the spring force will shift the valve spool, providing no air pressure signal is on the “B” end. By controlling the pressure differential between “A” and “B” a variety of applications are available.
