Product Description
About products
In the realm of severe service applications, characterized by high temperatures and significant differential pressures, SNT Machinery's multi-stage control valve trim offers unparalleled precision and longevity. Our advanced solutions ensure operations remain free from cavitation erosion and noise disturbances. Whether dealing with compressive or non-compressive fluids, this product series boasts a multitude of advantages. Enhanced performance and durability translate into reduced maintenance costs and streamlined system architecture, eliminating the need for additional equipment like diffusers and silencers. As a result, overall equipment expenses are minimized. With options ranging from 6862 to 7500 and 9000, depending on specific fluid conditions, the ideal model can be selected by evaluating both functionalities and pricing.
The multi-stage pressure-reducing labyrinth control valve features a core throttling component crafted from multiple stacked metal discs, intricately etched with labyrinth grooves. As fluid navigates through these channels, it encounters a series of collisions and directional changes that dissipate energy. This sophisticated mechanism not only manages flow rates but also systematically reduces pressure, making it ideal for high-temperature and high-pressure drop scenarios, such as those found in nuclear power and conventional power plants. While predominantly used for superheated steam, this valve is versatile enough to handle liquid mediums with equal efficacy.
