Valve sizing is critical to reach the best and optimal operation. For this purpose, paravalves engineering team works with Computational Fluid Dynamics to evaluate valve flow coefficient, thus the discharge flow value so a total control of the flow characteristic curve is achieved. This control, allows our team to size and redesign the valve to each project, making our solutions the most reliables in the market as all of them are sized to fit between the minimum and maximum flow working conditions of the project. Cone angle, face to face, flange and every other aspect of the design can be customized to reach the optimal solution.

As an additional accessory, a hood can be included to concentrate the valve outlet flow according to the customer's conditions. This accessory affects by reducing the discharge coefficient of the valve. 

Anti-cavitation design can also be performed, giving a total reliable solution improving the hood life.

Sometimes, it is required to work in operating points with a low degree of openness. In such cases, the fluid may reduce its pressure below the vapor pressure at certain points, thus producing the cavitation effect. This effect creates small implosions in the fluid in certain areas of the hood that deteriorate it. The paravalves technical team has been able to design a special design to avoid this situation for the hood.

At paravalves Dmmond SA push-though knife gate valves special top gate sealing concept is designed to ensure full tightness to the atmosphere even for gas or high pressure water applications.

Every design is fully hydrostatically tested at our facilities according to API 598, testing body cavity at 1.5 times the design pressure.

From optimized parametric design 3D modeling tools, to Finite Element Analysis (FEA) and Computational Fluid Dynamics (CFD) systems, our reliable fixed cone valves are ready to be manufactured with confidence.

Every component is designed and validated by top-notch softwares by the paravalves engineering team.
