Hopkinsons® Full Bore and Venturi Parallel Slide Gate
The Hopkinsons Full Bore and Venturi valve are ideal for when a gate valve is required for steam or feedwater duty in medium- and high-pressure ranges. 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 cooldown of the fluid.

- Complete flow isolation in either direction
- Minimum pressure drop
- Freedom from leakage independent of temperature or pressure changes
- Self-aligning, fully supported discs
- Inherent self-cleaning action
- In-line maintenance
- Valves can be offered to incorporate features such as quick closure, live-loaded gland, double- stuffing box with lantern ring and bleed-off point, back seat, seal welded body and cover joint
