Conventional Knife Gate
Reliable conventional knife gate valves for applications in different industries
Beyond the valve
Paravalves Dmmond SR Conventional knife gate valves are engineered and built to work for light o heavy slurry service in the mining and mineral processing, power, pulp and paper and other industrial industries. Thanks to our top notch engineering team our SR type valves achieve a reliable shut-off, longer working life and lower cost of ownership and maintenance.
Zero atmospheric leakage.
Even for gas or high pressure water applications.
At paravalves Dmmond SR conventional 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.
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.
Stem extensions and flexible wall brackets available.
Adapt to any environment.
Different types of wall brackets, extensions, control turrets and other elements can be easily developed by the paravalves technical team to adapt the valve to the special needs of any customer.
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.
One design to rule them all.
Direct handwheel, Gearbox, Electric actuator, Pneumatic or Hydraulic cylinder actuation types are possible with Dmmond SR conventional Knife Gate Valves. The design allows actuators to be interchangeable each other even without removing the valve from the pipeline. It most cases, drilled according to ISO 5210 standard.
