New Powertube(TM) Valve Technology Is Impervious to Contaminated Coolant and Pressure Spikes.


Pendell, PA (August 2007) - Co-ax valves' PowerTube(TM) technology is built into each of its HPB series valves. The company's coaxial valve technology isn't new. In fact it's been preferred among machine tool OEM's and users for a long time due to it's fast response time (< 900 ms depending on size) and the engineering and construction that makes it impervious to contaminated coolant.

But now the self-compensating, maintenance free design is also impervious to pressure spikes and does not require a pressure relief valve. Even when the valve is de-energized, the PowerTube(TM) is completely engaged. This feature keeps the line from draining and prevents any possibility of a dry start-up situation.

Machine tool coolant management comes down to two things: 1) Precisely regulated coolant pressure and flow and 2) Maintaining the functionality of the coolant in spite of graphite fines, metal chips, tramp oil and bacteria. The co-ax 3-HPB-S series does both.

About co-ax valves, inc.:
Headquartered in southern Germany, the company's North American operations are located in Philadelphia, PA. The company's solidly focused on debottlenecking flow related process and machine level valving problems. To do that we bring to bear an array of customized valve solutions integrating such features as bubble tight shut-off, bi-directional pressure-balanced designs, low energy and high cycle life, fast actuation, integral actuators and directly controlled valves that eliminate the need for internal pilot orifices. Many of these technologies and some of the designs are proprietary.

We know a lot about unusual and demanding applications. The exceptional accuracy and superior reliability of our coaxial PowerTube technology together with its huge operating range from vacuum to 7500 psi and from - 326°F to 756°F consistently allows us to debottleneck our customers' process or OEM design constraints.
