In the challenging realm of severe services marked by high temperatures and significant differential pressures, SNT's cutting-edge multi-stage trim stands as a beacon of precision and longevity. It adeptly tackles issues of cavitation erosion and noise, ensuring smooth operation for extended periods. Whether dealing with compressive or non-compressive fluids, this innovative solution is designed for seamless performance. This series boasts multiple advantages, including enhanced performance and durability, which collectively contribute to reduced maintenance costs and streamlined system design. Without the need for ancillary components such as diffusers and silencers, the overall equipment cost is significantly lowered. With models ranging from 6862 to 7500 to 9000, you can select the most appropriate option by evaluating both functionality and cost relative to specific fluid conditions.
The core of the multi-stage pressure-reducing labyrinth control valve is ingeniously engineered with multiple stacked metal discs embedded with intricate labyrinth grooves. As the fluid navigates through these labyrinthine channels, it experiences numerous collisions and turns, effectively dissipating energy. This meticulous process not only governs the flow rate but also gradually reduces pressure, making it ideal for high-temperature and high-pressure drop scenarios, such as those in nuclear power and power plants. Though predominantly used for superheated steam, it also accommodates various liquid mediums with ease.
