Dual Seal End Pieces

Motivation For years, IMI-Flow Design has provided valves with end connections customized for the job at hand.  When field disconnection is desired this means our carefully designed o-ring unions with their superior o-ring retention, but on system connections for an isolation valve a more permanent and tamper-proof system is required.

In short, of course it will make a difference, but it will not be worse than without the Autoflow™. Saturation The rate of heat flux from the


Traction Control

Picture yourself on a soggy dirt road. For some reason you’ve stopped and want to get going again. Unfortunately, when you press the gas, one wheel spins. Pressing the gas more just makes it spin more and the car goes nowhere. Then you suddenly remember your car has traction control and activate it. The system
