Key Specifications & Parameters Parameter Specification / Description Technology Type Advanced multi-stage, multi-path noise and cavitation control trim Design Principle Labyrinth disc stack technology creating sequential, controlled pressure drops through tortuous flow paths Noise Reduction Up to 25-50 dBA compared to standard single-stage trim Cavitation Control Exceptional cavitation protection - eliminates or severely minimizes cavitation damage even at pressure drops exceeding 5000 psi (345 bar) Pressure Drop Capability Designed for extreme pressure drops (up to 6000 psi/414 bar in some applications) Size Range Typically available for valves from 1" to 24" (DN 25 to DN 600) Compatible Valves Fisher cage-style globe valves designed for high-pressure service (e.g., ET, ES, HPT, and other severe service valves) Flow Characteristic Modified equal percentage inherent to the labyrinth design Materials Standard: 316 Stainless Steel High-Erosion Options: 17-4PH Stainless Steel, Stellite hard-faced components, Alloy 6, Other hardened alloys Temperature Range Limited by base valve materials, typically -150° to 1100°F (-101° to 593°C) Flow Capacity (Cv) Lower Cv compared to standard trim due to restrictive flow paths, but designed for maximum energy dissipation
