Sleeved Plug Valves

Specification Item	Technical Details & Standard Features
Design Standards	API 6D, API 599, ASME B16.34, ASME B16.10, ASME B16.5
Size & Pressure Range	NPS 1/2″ ~ 24″; Class 150LB ~ 1500LB
Plug Layout Variants	Inverted Pressure Balance Lubricated Pattern or Soft Sealing Non-Lubricated PTFE Sleeved Pattern.
Port Configurations	Short Pattern (compact face-to-face), Regular Pattern, Venturi Pattern, Full Bore (unrestricted).
Standard Features	Inverted pressure balance design balances line fluid dynamics to prevent plug seizure. Sealant injection system provides periodic refreshing of the micro-film seal under full line pressure. Sleeved variants feature 360° metal lip structural cage protection to secure the PTFE sleeve. Zero cavity area eliminates media entrapment, accumulation, or cross contamination. Self-cleaning edge action removes sticky, crystallizing, or high-viscosity surface scaling during cycles.
