Beyond the valve
At PARAVALVES, every product is carefully engineered as all the neccesary parameters are studied to develop our solid and reliable knife gate valves.
Double Gate knife gate valves are specially made for the pulp and paper industry, for pulp outlets or under silo applications. The design allows flow media with high consistency either for normal or reverse flow due to the bi-directional double seat design. The high flow coefficient value of this knife gate valve provides high flow rates with low pressure drops.
Customized valves
We design and manufacture customized solutions for each customer and need.

Even for gas or high pressure water applications.
At paravalves Dmmond SD Double gate 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.
Designed to cut through the fluid.
Special knife gate system for an optimum performance.
The two-piece construction bolted body retains two knife gates inside. In the open position, both gates are retracted into the body, providing a full bore design. When the gates closes, they push out the charged fluid out of the body and back into the flow. The stroke of this type of valves is reduced to a half, and so operating time is reduced as well.
Working under the most extreme condition Ni-Hard wear rings.
Protect the valve, work in any situation.
Ni-Hard wear rings or other special materials are available under request for extreme condition applications, ensuring best performance of the valve at heavy duty applications as well as a longer life for the equipment.
Engineered to last.
Even for extreme working conditions with abrasive fluids.
From optimized parametric design 3D modeling tools, to Finite Element Analysis (FEA) and Computational Fluid Dynamics (CFD) systems, our reliable knife gate valves are ready to be manufactured with confidence.
Every component is designed and validated by top-notch softwares by the paravalves engineering team.
