Valves that do not stick
2nd Quarter 2011
Pneumatic systems & components
The Bullet Valve (BV) series of solenoid valves from MAC Valves, supplier of air valve solutions to the filling industry, represents an evolution in air valve technology.
Speed and repeatability
A range of design features translates into filling performance benefits. The one piece poppet/armature (patents pending) gives balanced and repeatable strokes which are not affected by fluctuations in air pressure, while cushioning alleviates solenoid wear. D-Seal technology results in minimum friction, while the solenoid is isolated from any contaminated air. The calibrated strokes result in extremely repeatable response times and flow. The short stroke gives high shifting forces when the valve is energised, resulting in speed and reliability. These characteristics enable the valves to optimise cycle time and significantly improve fill level consistency.
Unique mounting
The mounting is unique, with no fasteners or screws required. The threaded cartridge configuration allows for a variety of mounting possibilities, such as direct integration into pneumatic actuators or vacuum generators, without the need for external tubing or fasteners. Both 2-way and 3-way models of the BV cartridge (9 mm and 10 mm diameter) are available. A surface manifold mount configuration is also offered.
There are very few parts, and the valve has an extremely long life. The ability for drop-in manifold replacement results in simplified field service.
Demonstration kits prove performance
These are backed up by high performance demonstration kits which prove the energise response time and repeatability of the valves. The Travelling Lab Demonstration (TLD) measures critical valve performance characteristics while the Proportional Lab Demonstration (PLD) function measures critical proportional regulation characteristics. They come with an animated software package which shows the inner workings of the various air valve designs. This is a powerful educational tool for demonstrating how air valves function.
