PTFE Lined Plug Valve
Salient Features
• Meet design specification as per BS 5353 / B 16.34 / Flange dimensions as per B 16.5
• Testing Standard as per BS - EN 12266 - 1 / DIN – EN – 588–1
• Lining Standard as per ASTM F 1545
• A one piece top entry PFA Lined Encapsulated taper plug design provides maximum corrosion resistance.
• The PFA body liner cover all wetted surface in the body and the plug extends are sufficiently cover as well.
• The solid taper anchored PFA Plug liner material ensures a strong adhesion.
• “T” – Slots matching will be a tight and perfect fit of the liner and additional support during vacuum service
• The Interface between the tapered outer plug and the tapered linear body provides a 360? primary sealing area.
• There are no cavities where flow media can accumulate or contaminate.
• In additional to large seating area the valve is fully bi-directional and the seal is totally independent of pressure.
• Large sealing surface from a port to port bubble – tight shut-off.
• A static eliminator which provides a positive electrical ground between the body and plug.
• A Secondary dynamic self adjusting PTFE “V” Rings prevents stem leakage.
• In line adjustment:- when seal presence adjustment is required due to sleeve wear, slight rotation of cover adjustment bolts. Pushes the plug downwards thereby providing extra sealing pressure / extra service life.
• Flow characteristics for control application.
• Full Port are assures low pressure drop and high flow characteristics.
