Product Description

About products

In the demanding environments characterized by extreme temperatures and significant differential pressures, SNT Machinery's exemplary multi-stage trim ensures precise control and offers an extended operational lifespan. It excellently mitigates cavitation erosion and noise concerns, regardless of whether the fluid involved is compressive or non-compressive. This innovative series boasts numerous advantages, as its enhanced performance and remarkable durability contribute to the reduction of maintenance expenses and system optimization. The elimination of ancillary components such as diffusers and silencers further decreases equipment investment costs. From models 6862, 7500, to 9000, tailored to varying fluid conditions, the most appropriate model can be selected by comparing functional capabilities and pricing.

The advanced multi-stage pressure-reducing labyrinth control valve incorporates a core throttling element crafted from multiple stacked metallic discs featuring intricate labyrinthine channels. As the fluid navigates these channels, it undergoes successive collisions and directional shifts, effectively dissipating energy. This innovative mechanism meticulously regulates flow rates while incrementally reducing pressure, making it ideal for specialized applications involving extreme temperatures and high-pressure drops, prominently within nuclear and power plant settings. This versatile valve primarily accommodates superheated steam as the working medium, yet is equally adept with liquid mediums.
