VENTURI VALVE

A reduced bore valve. A valve having a bore smaller in diameter than the inlet or outlet. For example, an 8″ x 6″ x 8″ ball valve has 8″ inlet and outlet connections, while the ball and seats are 6″. The flow through a venturi valve will be reduced because of the smaller port. Venturi valves can often be economically substituted for plug valves.
