Full Bore: The outstanding feature of the parallel slide design is that of maintaining fluid-tightness without the aid of wedging action. No mechanical stress is exerted between the discs, and there are no problems associated with cool-down of the fluid.
Venturi Design: The Venturi design is used when a slightly higher pressure drop is acceptable. The well established principle of fluid flow through a Venturi is used in order to minimise pressure drop. Venturi valves incorporate the design feature of an eye follower. In the fully open position the eye follower bridges the gap between the seats thus giving a smooth flow path and completing the Venturi profile.
