RE: How Commutating valve works

I have only ever seen them used in pipe flushing systems and reversing flow to backflush filters.

Sorry...can't help more than that...

RE: How Commutating valve works

That's a new one to me. What is a "Commutating Valve?" Is there other names for this valve that I might recognize?

RE: How Commutating valve works

Some examples of commutating valves are the valves in geroter  motors and valves in radial piston motors. These valves connect the pressure and tank ports at the correct time. Some are radial seal and some are face seal designs. The face seal can take up some wear if pressure balanced, but can be a problem if quick pressure changes occur. Radial valves require a close tolerance fit between the two parts. Both types require accurate location of the ports and will not tolerate contamination.

RE: How Commutating valve works

Thanks Ed for the clarification. I had never heard these valves called that or have lost it in my old memory banks. Seem to do a lot of that any more.

Research Report - What’s the State of Nonlinear Simulation?
Simulation is an increasingly valuable tool across the product design workflow, but not all simulations are equal. We set out to determine how engineers and product designers make use of specialized analyses, how they incorporate nonlinear simulation into their work and how they rate the available software.

White Paper – Data Security and Know-How Protection
Our data is constantly exposed to the danger of being intercepted or stolen as it wends its way over global data networks. Data security measures and measures for protecting intellectual property should not, however, first be implemented when data is exchanged – companies must lay the foundation for these measures within their own organization.
