Non Lubricated Plug Valve Gear Operated
MVS Two Way PTFE Sleeved or Non Lubricated Plug Valve Flanged Ends and Screwed Ends as per ANSI Class 150 and 300 is available in size range of 150 mm to 300 mm in Worm Gear Operation. Sleeved Plug Valve is available as Non Jacketed, Jacketed and 3 Way Port Designs. MVS Non Lubricated Plug Valve Body and Plug are available in materials like Ductile Iron, Alloy 20, Carbon Steel, SS 304, SS 316 etc.. We also offer wide range of Sleeve Options like PTFE, 15% RPTFE, 25% RPTFE, Glass Filled PTFE (GFT), Carbon Filled PTFE (CFT).
Sleeved Plug Valves provide tight shutoff from high vacuum through rated pressure at temperatures from -20°F to 600°F. As the plug rotates, the 360° port lips provide a self-cleaning action to remove scaling and adhering media.
The inert PTFE sleeve in our Sleeved Plug Valve completely surrounds the plug. The sleeve provides a large, circumferential sealing surface from port to port. Open, closed, or rotating, the seal is assured. No ball or gate valve can match this sealing power. The ptfe sleeve is securely nestled in the valve body. High pressure ribs, top and bottom retention, and 360° port lips all assure sleeve containment.
Standard jacketed ptfe sleeved plug valves are available in carbon steel or 316 stainless steel. Both Full jackets and Partial Jacket are rated at 235 psi at 400°F. Full jacketed valves have over-sized flanges.
