Pneumatic Ecosystem

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 (CE-CL-005-0003) and IO Expander (CE-MD-001-0001).

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)

When confirmation of the actuator position is needed, a Normally Closed (N.C.) position sensor (CE-SN-008-0001) 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 turned ON.

Up to 4 position sensors can be easily wired to a single Digital IO Module (CE-MD-001-0001). It should be wired as follows, the blue wire in GND input, the black wire in IN# input and the brown wire in the 24VDC input.

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.

6mm to 8mm inline One-touch Fitting	6mm 90 Degree One- touch Fitting to 1/8in RC with Speed Controller and Indicator	6mm Wye Splitter One-Touch Fitting	8mm Wye Splitter One-Touch Fitting	6mm OD Blue Tubing 5-meter Extension

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 8 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 C_v 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 C_v 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.
