PTFE Lined Ball Valve
MVS lined Ball Valve is generally made from Cast Ductile Iron with lining. PTFE Lined Ball Valves is a Full Port, Two Piece Split Body Design, Bolted Body Construction with Integral Ball and Stem Unit.
Other Features are DIN Face to Face, Replaceable PTFE Seat, Bubble Tight Shut Off, Glandless Design, Maintenance Free, Full Flow Efficient. Low Torque Manual lever Operated up to 100 mm / Worm Gear operated in 150 mm to 300 mm for easy operation.
The lining is securely locked into the deep machined groove slot into the pvdf lined ball valve body. And in holes in casting ball under melting processable of FEP or PFA. This prevents liner to collapse or blow out under full vacuum/high pressure applications & high temperature.
