Overview
OnSite Valve Technology is an important advancement in the pneumatics systems of the Wexxar machines which offers significant benefits for our customers.
Key Benefits
Reduces air consumption by 30% or more, and as a result, reduces energy consumption.
Key Differences
| Conventional Valve System | OnSite Valve Technology System | |
|---|---|---|
| Valve Location | Several feet away from the cylinders they control. Valves are located in a central valve bank & plumbed to each cylinder with extensive tubing (2-15 ft. of tubing each). In the illustration below, cylinder A is plumbed the height of the machine and is controlled by a valve in a central valve bank B.  | Within inches of the cylinders they control. No valve bank is used. We’ve eliminated approximately 60 feet of tubing per machine with our OnSite Valve design. In the illustration below, the same cylinder A is controlled by the OnSite Valve B. There is no valve bank so the valves are located as close as possible to the cylinders they control. The proximity conserves air and energy at a rate of 30% or more.  |
| Response Time | Air travels greater distances to actuate the valves and greater distances to exhaust. | Faster Response. Closer air intake & exhaust mean a more immediate response time, which in turn, means more ‘available time’ for machine actions—allowing for a more stable tuning. |
| Valve Size | 1.0 CV* Valve size has depended on the air pressure that travels from a greater distance. | Smaller & right-sized. 0.18-0.85 CV* Proximity of the valves & increased precision of air control allows for use of valve sizes that more exactly match each cylinder’s requirements. Right-sized valves offer additional air control & therefore less waste. |
| Definition: CV = Flow Coefficient; the flow capacity rating of a valve. A lower CV number means less air can flow through. | ||
| Valve Control for Setup & Testing | Cylinders can be actuated by the valve bank and via the HMI touch-screen. | Cylinders are actuated via the HMI touch-screen for troubleshooting convenience. |
| Air/Energy Efficiency | Approximately 20 SCFM** while forming 20 cases per minute. | 30% or higher air efficiency. Approximately 14 SCFM** at 20 cases per minute. Air is moved shorter distances. Smaller valves are used. Less air is required. Less air is wasted. |
| Definition: SCFM = Standard Cubic Feet Per Minute; the air flow rate by volume (at standard conditions of temperature & pressure). Lower SCFM means lower air consumption. | ||
