Plug Valve -- Lubricated & Non-Lubricated API 6D

Technical Datasheet -- Tapered Plug Valves for On-Off and Diverting Service

Document No.SV-DATA-PLV-001
RevisionA
DateMay 2026
ManufacturerSupreme Valves India, Ahmedabad, Gujarat, India

Lubricated and non-lubricated tapered plug valves for on-off and diverting service. Full-bore or regular-bore design with PTFE sleeve (non-lubricated) or sealant injection system (lubricated). Quarter-turn operation provides rapid actuation and clear position indication. Low operating torque due to PTFE sleeve or lubricant film. API 6D / API 599 / ASME B16.34 compliant. Multi-port diverter options available.
