LN82 Series Single-Seat Control Valve

The LN82 series represents one of the two fundamental pressure-unbalanced configurations in the LN8 product family. Featuring dual-guided bushings and seat design, it delivers exceptional flow capacity and outstanding dynamic stability. Its perforated cylindrical plug design effectively separates throttling functions from sealing surfaces, shielding the sealing interface from direct high-velocity fluid erosion to ensure reliable sealing performance. This innovative engineering achieves flash evaporation prevention, cavitation resistance, and noise reduction - making it particularly suitable for clean, high-velocity media applications, especially gas control with significant pressure differentials.
