Boom End Flush Valve Configurations
There are four different configurations of the boom end flush valve, tailoring each to the exact specifications needed to work perfectly.
Long/Short Handle Versions

We make two versions of each valve to accomodate a more compact handle (typically a -V0 part#), as well as a long handle version (a -LV0 part #).
The compact handle is convenient on boom ends that might have brush contact or have any risk of being caught on something. The long handle is for easier opening.
