THE COMPLETE POWER MODULE






ALLENAIR VALVE-IN-HEAD® CYLINDERS are unique, compact self-contained units combining Cylinder and Valve into one complete module. The base of the 4-way built-in valve is an integral part of the cylinder rear head, providing faster response and flow.

These units are space, time and cost savers in alI applications. Only one air connection is required and the built-in speed control screws enable fine adjustment of the extending and retracting stroke speeds independently. Consequently, pipe connections are reduced, reliability is increased and maintenance and installation costs are lowered.

The basic design features and materials are the same as found on the standard Allenair Cylinders and Valves on Pages 9 and 70.

Standard Stroke Lengths: Half-inch increments up to 3-1/2” and whole-inch increments from 4” through 20”. Special strokes available from 1/8” to 130”.

VALVE-IN-HEAD®
CYLINDERS

TYPE AV
All Type “AV” Cylinders are constructed using “O”-Ring Seals. Coupled with one of a wide variety of 4-way valves, these all purpose units are used for most pneumatic applications. Op- tional double rod packing is recommended for heavy duty applications.
Pressure Rating: 20 P.S.I. Minimum 150 P.S.I. Maximum


TYPE CV
Type “CV” Cylinders are constructed using low friction U-Cup Seals. A heavy duty wear strip (bearing) on the piston minimizes friction and piston cup wear, and on side load conditions prevents metal-to-metal contact. Coupled with one of a wide variety of 4-way valves, these units are primarily used on low friction applications and where low minimum breakaway is required.
Pressure Rating: 10 P.S.I. Minimum 150 P.S.I. Maximum


TYPE EV
Type “EV” Cylinders are constructed using Block-Vee Seals and include a heavy duty wear strip on the piston and double rod seals in the front head. Coupled with one of a wide variety of 4-way Valves, these Cylinders are recommended for heavy duty applications and where side load conditions are present.
Pressure Rating: 20 P.S.I. Minimum 150 P.S.I. Maximum

TYPE EVT
Type "EVT" Cylinders feature two Cylinders in tandem having two pistons mounted on one common rod (as Type "ET" on Page 11). Block-Vee Seals are used and include a wear strip on both pistons and double rod seals in the front head. The rear Cylinder has the advantages of an air operated Valve-in-Head® Cylinder, yet hydraulic control can be obtained by filling the front Cylinder with oil and piping its ports in series using a flow control valve.
Pressure Rating: 20 P.S.I. Minimum 150 P.S.I. Maximum
BASIC CONSTRUCTION (VALVES)
The valve portion of the Valve-in-Head® Cylinders is corrosion resistant slider type 4-way 2-position valves. The valve base is hard coated aluminum, lapped within one light band, and electro filmed. This provides minimum slider wear, positive seal and millions of trouble-free cycles. A durable delrin spool rapidly pilots the high-tensile manganese bronze slider across the enlarged internal ports changing direction of flow. The built-in side tubing provides air passage to the front end of the Cylinder. These Valves are available as Solenoid, Pressure Pilot, Bleed Pilot, or Manual Models.

SINGLE SOLENOID


MODEL SVEVA

These models incorporate a 4-way Single Solenoid Double Bleed Pilot Valve. A momentary (NOT continuous) electrical contact is required to move the rod its full stroke. A Bleeder Valve, such as the Allenair BV100 or BV-1/8 (to be ordered separately), must be connected to the spool cap opposite the solenoid. Depressing this Bleeder Valve momentarily will return the rod to its original position. Models can be supplied with the rod normally retracted (electrical contact will extend rod) or normally extended (electrical contact will retract rod). The standard solenoid operator, as shown is the AAS splice box housing.

DOUBLE SOLENOID


MODEL SDS

These models incorporate a 4-way Double Solenoid Pressure Pilot Valve. A momentary or maintained electrical contact applied to one solenoid will move the rod its full stroke. The rod will remain there under pressure until the other solenoid is energized, which will cause the rod to return to its original position. If a maintained contact is employed, the first solenoid must be de-energized before the other is energized.


The standard soleniod operator, as shown is the AAS splice box housing.

DOUBLE PILOT


MODEL AP
This model incorporates a 4-way Double Pressure Pilot Valve. A momentary or maintained pilot pressure applied to one side of the valve will move the rod its full stroke. The rod will remain in that position under pressure until a pilot pressure is applied to the other side, which will cause the rod to return to its original position.

If a maintained pilot pressure is applied, it must be released before the other pilot pressure is applied. Pilot pressure must be at least 25% of the operating pressure.


Bore Sizes Available: 1-1/8”, 1-1/2”, 2”, 2-1/2”, 3” & 4”.

DOUBLE PILOT


MODEL SVA

This model incorporates a 4-way Double Bleed Pilot Valve. A Bleeder Valve, such as the Allenair BV100 or BV-1/8 (to be ordered separately) must be connected to each spool cap. Depressing one Bleeder Valve momentarily will move the rod its full stroke. Depressing the other Bleeder Valve momentarily will return the rod to its original position.

These Cylinders are available with1-1/8” bore only. They are Single Acting Cylinders controlled by a 3-way Single Solenoid Valve mounted to the rear head of the units. The standard solenoid operator, as shown is the AAS splice box housing. A general purpose conduit lousing (AAC) is also available. Most common AC & DC voltages are available. 12, 24, 120 & 240/60 and 6, 12 & 24VDC are standard. The basic constructions are that of our 1-1/8” bore Type "A" Cylinders.

TYPE AVSA A continuous electrical contact is required to fully extend the rod, which will remain extended until the electrical contact is broken. An external force is required to return the rod to its original position. A 1/8” N.P.T. port is provided in the front head to permit the return of the rod by means of a separate air supply if required. This port can also be used to install a Flow Control Valve to control forward speed. Standard stroke lengths are whole inch increments from 1" through 20” and 1/2", 1-1/2", 2-1/2" and 3-1/2" . Special strokes available from 1/8” to 80” maximum.
