Wafer And Lug Type Fep/pfa /Ptfe/pvdf Lined Butterfly Valves

These Wafer and Lug Type FEP/PFA /PTFE/PVDF Lined Butterfly Valves has been used in the most aggressive and corrosive applications like hydrofluoric acid, sulfuric acid, 35% hydrochloric acid, nitric acid, chlorine gas (wet or dry), vinyl chloride monomer, ethylene di chloride, chlorinated caustic soda, chlorine dioxide, bleached stock and sodium chlorate among others; as well as ultra-pure applications such as 18 Mega OHM de-ionized water and ultra-pure HF acid.
These Wafer and Lug Type FEP/PFA /PTFE/PVDF Lined Butterfly Valves for aggressive chemical and ultra-pure applications. FEP resists chemical attack from most known chemical compounds, and with a flexible liner design utilizing a full width, 360A degree, resilient back up liner offers bubble tight shut off in even the most demanding installations. Redundant shaft seals (which include a spring energized safety packing) provide a tight, reliable seal to the environment.This is a a maintenance freea valve design which uses long life sleeve bearings And avoids the use of an adjustable packing gland.

Valve is rated up to 150 psig and down to 0.0002 psia (full vacuum). It is available in either a ductile iron wafer or ductile iron lug body.
