The new Velocity Expulsion Valve works in combination with
Velocity’s standard mounting plate and is hidden in the distal end
of the socket. The use of a dummy during lamination creates a void
in the distal end of the socket that accepts the Velocity valve.
The valve has a large duckbill for quick air expulsion and easy
cleaning. Unique to the Velocity valve is the ability to replace
the rubber duckbill without the need to purchase a new valve
