How Commutating valve works

How Commutating valve works

Hi guyz,

I wanna know functioning & application  of Commutating valve.

Thanks before

with regards

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.

White Paper - Effects of AIA Quick Guide to UL 489 or UL 1077
The function of a circuit breaker is to provide overload (thermal) and short-circuit (magnetic) protection to a circuit and its downstream components. A circuit breaker functions like an airbag in a car, protecting circuit components and people by tripping the circuit to interrupt the current flow if it detects a fault condition in the control system.

White Paper - Guide to Integrate Large-Format Additive
As with any new technology, getting into large-format 3D printing begins with investigation. The first question may be a simple one: what does “large-format” mean? For 3D printers, “large” is a relative term. Many extrusion-based (FFF) 3D printers are referred to as desktop machines, because they fit on table space. Some of these have very respectable build volumes – but when it comes to “large-format,” the machines will need their own dedicated floor space. Large-format 3D printers have significant build volumes and are most often found in professional settings, like manufacturing facilities and R&D centers. Download Now
