Product Description

Technical Specifications:
Operating pressure: 150 psi (10.3 bar) max.
Temperature range: -40°F to 160°F (-40°C to 71°C)
Ports: 1/4" NPTF
Mounting: integral mounting lugs
The six and seven position cylinders are medium duty pneumatic positioning devices that operate through six or seven pre - determined positions of 1/2" (12.7 mm) increments with total strokes of 2 - 1/2" (63.5 mm) or 3" (76.2 mm) respectively. They were primarily designed for power - shift indexing on mechanical transmissions, but are also suitable for indexing increments are required. The fixed stroke six or seven position valve. AVENTICS "P" Rotair is an electro - pneumatic switching circuit using 3 - way solenoid valves. These cylinders are extremely rugged, having anodized, corrosion - resistant, lightweight aluminum body, piston and piston stops. 
Installation
Mount the cylinders in any desirable plane to a sturdy, flat surface (preferably with the ports facing down) with three 3/8" bolts. Mounting lugs are cast into the cylinder body. Extreme care should be used in binding will affect the service life of the rod bearing and piston stop seals.
All ports are 1/4" - 18 NPTF. The following ports should be piped together with "T" connections: 3 with 3A on the six position cylinder, 3 with 3A and 6 with 6A on the seven position cylinder.
Connections should be made as close to the cylinder as possible to reduce the number of lines from the control valve.
 
Operation
Maximum operating pressure is 150 psi (10.3 bar) at a temperature range of - 40°F to 160°F (- 40°C to 71°C). The cylinder piston rod reaches its various positions in response to pressure being supplied to the cylinder ports as shown in the porting diagrams. V means air must be vented to atmosphere, S means air must be supplied and S/ V means port can be supplied or vented, whichever is most convenient at the control valve. Each of the cylinder has reverse full extended position of rod and is spring returned to neutral (next position from reverse) from any position. The transmissions which these cylinders usually control have the full automatic or drive position adjacent to reverse, the next operating position is 2nd, then 3rd, 4th, 5th and 6th in the seven position and 4th in the six position cylinder.

The sequential order of cylinder position is a function of the "P" Rotair valve.
Control Valve Notes: "P" Rotair valve

R431006324 was designed to control six position cylinder R431006322 and valve R431006326 was designed for seven position cylinder R431006321. Both of the Rotair valves have first gear position adjacent to neutral and progress toward full automatic (see catalog SC - 700).
 
Six position Rotair R431006324 should be connected as follows: port no. 1 & no. 5 plugged, exhaust port is 1/8" NPTF, pressure is supplied to cylinder port no. 2, valve no. 3 to cylinder valve no. 4 to valve no. 5, valve no. 3 to cylinder no. 2, valve no. 3A, position cylinder no. 6 to cylinder port no. 6A in six and valve port R431006322.
 
Seven position Rotair R431006326 should be connected as follows: port no. 1 plugged, exhaust port is no. 4, pressure is supplied to unnumbered cylinder port no. 2, valve no. 3 to cylinder no. 2, valve no. 3 to cylinder no. 3A and 5A, and valve port no. 6 to cylinder no. 6 and 6A in seven position cylinder R431006321.
 
The forces developed by the cylinder are functions of the air pressure applied to the exposed piston area and are tabulated for rod movement at the various stroke positions as shown on the charts on following pages. The internal spring returns the piston rod to its "Neutral" position when air pressure is intentionally or unintentionally exhausted from all control lines. This safety feature returns the transmission to neutral if the air supply is lost.
