Product Description

About products

Experience unparalleled performance with SNT's Durable Cage Guided Globe Valves for High Pressure Systems. Designed for the most demanding environments of high temperature and high differential pressure, our state-of-the-art multi-stage trim ensures precision control and exceptional longevity, effectively eliminating challenges like cavitation erosion and noise disturbances. Whether dealing with compressive or non-compressive fluids, this series excels, enhancing performance and durability to significantly lower maintenance costs and streamline your system operations. With the elimination of ancillary equipment, such as diffusers and silencers, you'll see a notable reduction in equipment costs. Our range of models, from 6862 to 9000, caters to various fluid conditions, allowing you to select the ideal model by comparing functionality and pricing.

At the heart of our multi-stage pressure-reducing labyrinth control valve is an innovative core throttling component made from multiple stacked metal discs with expertly engineered labyrinth grooves. As fluids navigate through these intricate channels, they engage in multiple interactions that dissipate energy-this precision technique governs flow rates and gradually reduces pressure. Ideal for specialized applications in nuclear power and power plant settings, where high temperature and high-pressure drops are prevalent, these valves are optimized for superheated steam and adaptable for liquid mediums too.
