Increase Vacuum Packing Machine Speed with Dale Valve Solutions

Vacuum packaging is a process where a product is placed in a bag or sandwiched in-between two sheets of plastic, a vacuum is applied to remove atmospheric air and then the product is sealed. In an effort to increase machine speed, valve port sizes generally range from 1” to 2-1/2”.

 

Vacuum Pack 1

 

Our customers have had great success using Dale Series valves in their vacuum packaging applications. A leading OEM tested the Dale series and reported:
Vacuum Pack 2

“The valve reduced the time to evacuate the sealing die in a head to head test with our current valve. The power consumed by the vacuum pump was also reduced 6% at 10 cpm.”

Reduce Thermoforming Cycle Time with Dale Valve Solutions

Thermoforming 1

Thermoforming is a process where a thin sheet of plastic enters the machine mold and forms thin walled products by vacuum being pulled on the mold. These machines produce high volume, low margin products, and machine speed is the difference between profit and loss.

The Dale Valve Solution from ROSS Controls

  • Compact Manifold Design- eliminating piping allows mounting closer to the mold
  • Reduced Cycle Time- Less piping = less volume to evacuate = speed = profit
  • High Flow- CP series 2-1/2” with a Cv of 100 = massive speed = massive profit
  • Fast Consistent Shifting- Dual piston design eliminates springs and provides smooth, fast shifting
  • Energy Savings- The Dale Valve Solution is Green!Thermoforming 2
    • Reduced piping eliminates system volume which reduces vacuum pump and compressor drain
    • True 2/2 Dale design with no “open crossover” reduces vacuum pump and compressor drain
  • Reduced Downtime- Poppet cartridge design allows rebuilds to be completed in minutes

Reduce Leak Testing Cycle Time with Dale Valve Solutions

Practically every pressure-containing vessel is leak tested during production or assembly. There are generally three types of leak test methods: pressure or vacuum decay, flow tests, and helium tests.

You might ask, “Why are the valves used in testing so important?” Essentially, if the valves being used to control the test themselves are leaking, you won’t be able to tell if the product under test is leaking.

Reduce Tray Pack Process Time with Dale Valve Solutions

Tray Pack 1

Tray packing is a modified atmospheric packaging process where a product is placed in a tray, a vacuum is pulled to remove atmospheric air, inert gas is injected, and the tray is sealed. The process helps to extend shelf-life, enhance color, and eliminate crushing.

Pilot Operated Check Valves for Cylinder Position Holding

PO1

Cylinder applications must consider what happens to the application’s safety function with the loss of air pressure.

Pilot Operated Check Valves, otherwise known as PO Checks, are used wherever a high-flow or remotely-controlled checking function is needed to provide cylinders to automatically stop in the event of the loss of electrical power or system air. (more…)
