VIDEO TRANSCRIPT:

Hi there, I’m Mike Kettering, product manager for electronic valves here at �ǳ�web. Today, I’d like to talk about how a basic leak decay tester works. A basic leak decay tester takes pressure, applies that to a volume, isolates that, and watches for a change over time. The data that is acquired from this tester can be used to calculate a leak rate. Using a 3/2 and a 2/2, also known as a 3-way and a 2-way valve, in series can isolate the pressure in a volume. This simple two-valve circuit, when used in conjunction with a pressure sensor, can be a basic leak decay tester. This circuit can be combined with a PLC to produce additional functions.

�ǳ�web’s EV spider valves have a reputation for being the best in class when it comes to leak resistance. �ǳ�web’s A-, also known as the analytical version, modifies some of the components and processes to maximize that performance.

When testing for leaks, you need confidence that your equipment is up to the job. A leak tester is kind of like a chain—it’s only as strong as the weakest link. �ǳ�web valves are the perfect partner for any application where leak resistance is imperative.

Applications

A leak is defined as an unintended passageway that enables fluid to escape plumbing, a component or a system. There are a number of methods used to detect leaks such as pressure decay, mass flow, bubble, sniffing and vacuum.

pressure decay technology

�ǳ�web utilizes pressure decay technology, and integrates automatic leak testing circuitry into our assembly equipment. We use our EV/ET, DV and EM series electronic valves to fill and hold pressure because they are bubble tight, do not generate heat, and have a billion cycle life expectancy.

The Analytical Series has been designed specifically to reduce and limit potential leak paths within the valve.

reliability & accuracy

For reliable, accurate leak test equipment designs, �ǳ�web provides:

• High flow valves capable of filling large volumes quickly

• Built-in pneumatic circuits that automatically switch leak
tests from one side of a part to another

• Optimized systems for multiple test pressure
requirements, etc.

• Custom assemblies including valves, cylinders,
regulators, fittings and more.

�ǳ�web’s miniature valves, actuators, fittings and regulators are ideal for these types of applications.
