We recommend the highly versatile Hopkinsons® Flexi Wedge design as gate valve which is designed for containment isolation duties.
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.
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 minimize 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.
General purpose stop valve
Main steam and feedwater isolation
Boiler circulating pump isolation
The basic design is also incorporated in valves for other duties such as: Feedwater heater protection; Feed pump leak-off; Nuclear Applications (ASME Section III, Class 1, 2 & 3); Oil & Gas applications upstream, midstream, and downstream
