Features & Benefits
Cage-Guided Plug Design
Cage-guided piston plug provides stabilised guidance, preventing stem vibration and plug chatter at high pressure drops. Multiple cage windows enable characterised flow profiles (linear, equal percentage, quick-opening).
Anti-Cavitation Trim Options
Multi-stage pressure-reducing cage or drilled-hole plug dissipates pressure drop across multiple stages, preventing cavitation damage in high-pressure differential liquid service.
Anti-Noise Trim Options
Multi-path cage with numerous small flow passages reduces jet velocity and turbulent mixing, lowering aerodynamic noise in high-pressure gas service by up to 30 dBA.
Smart Digital Positioner
HART / Fieldbus / Profibus-compatible smart positioner provides auto-tuning, adaptive gain, valve signature diagnostics, and predictive maintenance alerts via asset management software.
Class VI Soft Seat Option
PTFE / RPTFE soft seat insert achieves ANSI/FCI 70-2 Class VI bubble-tight shutoff for applications requiring zero leakage during closed periods.
Extended Bonnet Options
Extended bonnet for high-temperature insulation, cryogenic service (-196 deg C), or bellows seal for zero fugitive emissions (TA-Luft / ISO 15848-1 compliant).
