Overview
Vention has partnered with SMC, an industry leader in pneumatics, to bring you a series of pneumatic components. These components include an air preparation station complete with a pressure regulator, air filter and manual safety release valve, a manifold that supports up to four independent open-center valves that drive various lengths of double-acting cylinders. The entire system is controlled using Vention’s MachineMotion 2 (CE-CL-010-0004) and Digital I/O Module v2 (CE-MD-001-0000__2).

Wiring
Every Manifold Station comes pre-wired with M12 4-pin female connectors. Each M12 connector allows the control of a single valve output, with each valve having 2 outputs (A and B). Since a Digital I/O Module v2 (CE-MD-001-0000__2) has 4 outputs ports, up to 2 valves can be controlled by a single module. Simply connect every M12 connector to a digital output port (follow the labeling) and start controlling the manifold out-of-the-box.
Valve and output numbering goes as follows on the manifold station:
A 2-Valve Manifold Station (CA-CO-001-0002__2) cable has 4 labeled M12 connectors that control valve outputs as follows:
A 4-Valve Manifold Station (CA-CO-001-0004__2) cable has 8 labeled M12 connectors that control valve outputs as follows:
Each valve has a LED indicator reflecting the state of its outputs:
Indicator color | Valve state |
---|---|
OFF | Both outputs are de-activated. No air flows through A nor B. |
RED | Output A is activated. Air flows from the intake to A. |
GREEN | Output B is activated. Air flows from the intake to B. |
RED AND GREEN | Both outputs A and B are activated. No air flows through A nor B. |

The pivoting non-guided actuator force is a function of its operating pressure. The theoretical output force can be calculated in the Actuator Force Calculation section below.
Additionally, the pivoting non-guided cylinders have rotational limitations on both front and back clevis brackets. The front piston clevis mount of the cylinder is limited to a ± 50° range of motion, while the back clevis mount is limited to ± 40°.
Position Sensor (CE-SN-008-0001__2)
When confirmation of the actuator position is needed, a Normally Closed (N.C.) position sensor (CE-SN-008-0001__2) can be easily slid into any groove on the pneumatic actuator and secured in place using a 1mm precision flat screwdriver. It accurately senses the magnetic field of the piston as it passes beneath the sensor and a built-in red LED illuminates when the sensor output is active.
Each position sensor can be directly connected to a Digital I/O Module v2 input port (CE-MD-001-0000__2), up to 4 sensors per module.
The guided actuators (MO-AR-002-0100/0200) require an adapter to properly secure the position sensor in place. An adapter is included with each sensor.
Accessories
Vention’s Pneumatic Ecosystem also includes a variety of accessories for different use cases.
The 6mm 90 Degree One-touch Fitting to 1/8in RC with Speed Controller features a numeric indicator representing a specific level of flow control for cylinders. This fitting can be used to slow down and control the speed of the push and pull movement of our dual action cylinders. The indicator can be used to synchronize multiple cylinders to the same speed.
Note: The speed controller fittings replace the pre-installed 90-degree fittings on all our cylinders. When installing the speed controller fittings, the cylinder must be turned either 90 or 180 degrees with respect to the mounting brackets as the fittings do not fit underneath when mounted. Use an adjustable wrench to properly install the fittings.
Assembly Instructions
Note: All air supply tubes have an 12 mm outer diameter, whereas all actuator tubes have a 6 mm outer diameter.
When connecting your pneumatic system:
- Make sure the emergency shutoff valve is turned to the EXH (exhaust) position
- Connect the filter/regulator unit’s outlet to the manifold’s inlet port using the provided 8 mm tubing
- Connect the unaltered end of the provided supply line to the shutoff valve’s inlet
- Attach the provided quick-connect fitting to the supply line, and connect the end of the fitting to your air supply
- If you don’t have an air-preparation station, simply connect the unaltered end of the provided supply line to the manifold’s inlet
Every valve features two ports which correspond respectively to the actuator’s push and pull actions
- Connect the valve ports on the manifold to the actuator ports using the provided 6 mm tubing
- Test the actuator. If the direction of action is the opposite of what is desired, simply swap the tubes using the one-touch fittings

Actuator Force Calculation
The effective pushing and pulling force of all cylinders can be calculated as follows:
Pressure P [MPa] | 0.3 | 0.5 | 0.7 |
Non-Guided Cylinder Pushing Force (Out) [N] | 241 | 402 | 563 |
Non-Guided Cylinder Pulling Force (In) [N] | 181 | 302 | 422 |
Guided Cylinder Pushing Force (Out) [N] | 147 | 246 | 344 |
Guided Cylinder Pulling Force (In) [N] | 113 | 189 | 265 |
Flow Rate Calculation
Your system’s maximum Flow Rate Qv in standard cubic feet per minute (scfm) can be calculated by deviding the Flow Coefficient Cv by a predertermined conversion factor based on pressure as seen in the table below.
Pressure P [MPa] | 0.276 (40 psi) | 0.345 (50 psi) | 0.412 (60 psi) | 0.483 (70 psi) | 0.552 (80 psi) | 0.621 (90 psi) | 0.690 (100 psi) |
Conversion Factor | 0.0370 | 0.0312 | 0.0270 | 0.0238 | 0.0212 | 0.0192 | 0.0177 |
When calculating the maximum flow rate, it is important that the lowest Cv value is used as it is the limiting factor. For example, to determine the maximum flow rate through a system that utilizes an On/Off Valve (CE-AR-002-0000) and an Air Preparation Station (CA-AP-001-0001), the lowest Cv is 2.1. Assuming the system’s pressure is set to 0.55 MPa (80 psi), the following calculation must be done:
Note: This general rule applies at standard air temperature (20°C) and pressure (101.3 kPA or 14.7 psi). It provides an approximation of air flow rate values, not an exact measurement.
