Vortex Hydra from project quotation/initiation stages place much emphasis on the values of the successful packaging and transportation of the plant and equipment. The company recognise the importance of obtaining the perfect transport conditions which includes the optimisation of cargo dimensions for safe movement of plant and equipment together with the most cost efficient solution. Having vast worldwide …
The Stop Logs are custom designed steel bulkheads that are used in channels or control structures to hold back the flow of water. They are individually lowered on top of one another via a vertical guide system to a pre-determined height, to suit the dimensions of the sluice that they are restricting the water flow through. The design of the Stop Logs is a single rectangular unit that can be used in single or modular format to…
Navigation Locks (or Pound Locks) are used on canals, rivers and dams to allow boats to bypass any obstructive structure in its navigational path and/or for the raising and lowering of boats between stretches of different water levels.The Navigation Lock is normally a long narrow constructed canal type structure of suitable dimensions to allow a boat to pass through it. Steel Gates (called “Mitre” or “Miter” Gates)…
The Bottom Outlet Gates are high pressure gates that are employed as a safety device during general maintenance operations – their specific wide dimensions allow the dam basin to be emptied very quickly.Located at the bottom (or “low level”) of the dam’s basin, they consist of a pressurised pipe that is closed by twin sliding gates, that allow water to pass through even when partially open.The concept of twin operating…
The Radial Gate (also called Tainter Gate or Taintor Gate) is a different type of floodgate used to control the water flow through dams and canal locks. This type of floodgate is raised and lowered by radial arms located on either side of the gate.The design of the Radial Gate consists of a suitably reinforced rolled steel skin plate that has two structurally designed radial arms located on either side. The pivoting radial arms…
Flap gates (also called Tilting Gates) are mainly employed to control the flow of water through flood barriers, reservoirs and rivers.Flap gates are of a heavy duty structural design consisting of a steel reinforced skin plate the outer side of which is loaded against the water pressure when the gate is in a closed position.The Flap Gates are designed to operate in a vertical position whereby they restrict the main flow of water…
The Fixed Wheels & the Slide Gates are two type of Floodgates mainly used to provide a vertical water barrier in waterworks, inside a pressured system or in open water channels. Both these Floodgates can also operate in a partially opened position to control water flows.The ‘opening/closing’ mechanism can consist of wheels being mounted in the vertical sides of the gates that move up and down within fixed side guides so…
The Fixed Cone Valves (also called Free Discharge Valves) are mainly used as an alternative to Hollow Jet Valves in applications that require water to be freely discharged into the atmosphere at controlled rates. This type of valve dissipates enormous amounts of energy by breaking down the water into a large, hollow expanding jet.The Fixed Cone Valves are designed to operate at variable controlled flow rates between fully open…
Vortex Hydra design and manufacture both mono-plane and bi-plane (lattice type) Butterfly Valves depending on the dimensional requirements and operating water pressures. As a special application a secondary maintenance seal system that is mechanically actuated (rubber seated in metal) can be implemented. The Butterfly Valves are manufactured with the combination of steel plates and forged components. Vortex…
The Spherical Valves are mainly employed in power plants or dams where both water high pressure is involved and the need for high performance for low head losses and leak tightness exists. A common application is ‘turbine protection’, where the valve acts both as safety and maintenance device.An important feature of a spherical valve is the ‘double seal system’, consisting of both maintenance and service stainless steel seals…
