Valves for leak testing
Perhaps the most important factor in leak testing is the valve used to leak test. If the valve is not reliably leak tight itself, the testing efforts are a waste of time. ROSS’ high-flow, bubble tight Dale Series LT, CX and LX valves and manifolds have patented poppet design and exceptional sealing capabilities.
The Dale Series LT, CX and LX valves help streamline processes with their high flow (thus reducing testing time) and offer a broad pressure range of high vacuum up to 250 psi for flexibility. The LT, CX and LX valves are pressure independent so that pressure or vacuum can be applied to any port at any time. The valves feature low wattage coils that reduce energy consumption and help avoid unnecessary valve heat. For further convenience, these bi-directional valves are offered with compact manifolds which eliminate piping (and potential leak paths) and spacing between valves, and provide simplified installation.
Beyond their basic leak testing proficiency, the Dale Series LT, CX and LX valves are versatile and provide many application-specific benefits. In channel select applications, for example, customers are able to test multiple parts at a time or multiple chambers in a single part. And with bypass fill and exhaust applications, the Dale Series valves’ high-flow design can improve cycle time and be used as an exhaust valve, helping prevent contamination to other units.
