Flow Characteristics And Regulation Performance of J-VALVES High-pressure Sealed Globe Valves.

In the field of high-pressure fluid control, J-VALVES high-pressure sealed globe valves demonstrate numerous remarkable advantages thanks to their outstanding flow characteristics and regulation performance.

In terms of flow characteristics, they have a strong adaptability to nonlinear flow characteristics. In the small opening range, for example, when the opening degree is between 0 and 20%, the slight lift of the valve disc can make the fluid passage expand progressively, and the flow rate change rate is controlled within a very small range. This effectively avoids the fluid impact caused by the "on-off jump" of traditional valves, which is extremely crucial for precise operations such as the accurate injection of catalysts in chemical reactors. In the medium opening range (20% - 80%), there is a highly linear relationship between the flow rate and the lift of the valve disc with a minimal error, ensuring the precise and stable flow of steam in industrial boilers and the feed ratio in petroleum cracking units, keeping the process parameters in an ideal state all the time. When the valve is in a large opening state, relying on the streamlined inner cavity and symmetrical flow channel design, the turbulence is reduced, and the pressure drop can be 15% - 20% lower than that of similar products, achieving significant energy-saving effects and being especially suitable for long-distance high-pressure gas transmission pipelines.

Regarding the regulation performance, the advantages are equally prominent. The multiple drive systems work in intelligent collaboration. The manual drive, equipped with a high-precision worm gear transmission mechanism and a scale dial, enables millimeter-level precise adjustment. The electric drive integrates an intelligent actuator with fast response and accurate positioning, which is suitable for automated control. The hydraulic or pneumatic drive performs excellently in ultra-high pressure and high-frequency regulation scenarios. Meanwhile, a perfect balance is achieved between sealing reliability and regulation flexibility. The cemented carbide sealing pair is wear-resistant and has good sealing performance. The self-lubricating valve stem system reduces friction, and the mass-optimized valve disc can suppress flutter. Facing extreme working conditions, the anti-erosion flow channel hardening treatment and the anti-blocking valve disc structure enable the valves to operate stably and reliably in complex media.

In conclusion, J-VALVES high-pressure sealed globe valves, with their advantages in flow and regulation performance, provide high-quality and reliable solutions for numerous high-pressure fluid control scenarios.
