Product Description

About products

In the demanding realm of high-temperature and high differential pressure services, the SNT User-Friendly Cage Guided Multi-stage Limiphon Control Valves excel with precision control and extend their lifespan significantly. They effectively eliminate concerns of cavitation erosion and noise problems, ensuring a reliable performance, whether dealing with compressive or non-compressive fluids. This series offers multiple advantages, notably enhanced performance and durability, which lead to reduced maintenance costs and a streamlined system. Without the need for additional components like diffusers and silencers, the overall equipment expense is reduced. Choose from models 6862, 7500, or 9000, tailored to fit specific fluid conditions, allowing for optimal function and cost effectiveness.

The innovative multi-stage pressure-reducing labyrinth control valve features a core throttling component crafted from multiple stacked metal discs intricately designed with labyrinth grooves. As fluid navigates through these channels, it experiences numerous collisions and turns, effectively dissipating energy and controlling flow rate while methodically reducing pressure. Ideal for environments with high temperature and pressure drops, these valves find their place in nuclear power and power plants, handling mediums like superheated steam and, at times, liquid mediums too.
