coax valves for demanding hydrogen applications

For reliable performance, flexibility and endurance, manufacturers of hydrogen equipment require valves which can deliver an extended cycle life with minimal space requirements and bubble tight shut-off capability.

To meet these stringent requirements, leading manufacturers rely on co-ax® valves, which are not like any other valves you’ve encountered in your career.

The reason why co-ax® valves perform so flawlessly under extreme conditions is that the valves' operation is pressure-independent. In a co-ax® valve, the control element is always pressured balanced, regardless of whether it’s open or closed.

This unique design allows a co-ax® valve to cycle more quickly with positive, leak-free shutoff. As a result, co-ax® valves can last up to ten times longer than conventional ball or diaphragm valves, while requiring virtually no maintenance throughout their extended life cycles.

Why choose co-ax® valves?

In a co-ax® valve, media flows straight through the valve without any significant deviation of the media. Due to the pressure balanced design, the necessity of an internal pilot orifice is eliminated. This makes the valve less susceptible to contamination and solid particles and provides higher flow rates with a minimized pressure loss.

The combination of compact size, bubble tight design and long cycle life makes co-ax® valves the ideal replacement for actuated ball valves, angle-seat valves, motor driven valves and conventional solenoid valves especially in remote or difficult to service applications.

co-ax® valves have only one moving part which greatly reduces actuation forces and operational stresses. As a result, co-ax® valves can last up to ten times longer than conventional valves, requiring virtually no maintenance throughout their extended cycle life.

Co-Ax Valves for special applications

No warmth. No rest. No contest. 

with Co-Ax Valves.

KB-15 co-ax valve

The powerful control tube design from co-ax® wasn’t the first valve specification in this application. But it was the last one. In fact our customer documented that the co-ax® cryogenic valve outperforms the valve it replaced by 300%. This level of routine performance has an obvious and positive impact on (a) reduced downtime, (b) reduced maintenance, and (c) reduced spare parts inventory.

In this low temperature, high cycle application, the co-ax® KB 15 valve is applied as an on/off valve to maintain an exact temperature of –65º F in the isolation chamber. Maintaining a positive shut-off under these conditions is crucial to the accuracy of the chamber.

Although this application didn’t really test the –326º F range of the co-ax® technology, it might not have been quite the right valve were it not for the valves’ low profile design. This last feature proved to be an essential benefit in the compact system controlling the precise temperature in the bench top chamber.

We know a lot about unusual and demanding applications. The exceptional accuracy and superior reliability of our coaxial power tube technology together with its huge operating range from vacuum to 7500 psi and from -326°F to 756°F consistently gets us involved in some real valving adventures. But we’re committed to helping our customers out of every demanding application they get themselves into.
