Parker Metric Ball Valves Series BVGC
Principle
Parker BVGC series economy ball valves
are designed for use in a wide variety of fuid
applications. Available with BSPP female/
female* short threads to ISO-228, they are
full fow valves giving minimum pressure
drop. The BVGC series has a double PTFE
seal on the ball enabling the valve to be used
with fow in either direction. All seals are
treated with a silicone free lubricant enabling
the valves to be used in water-based paint
spray applications. BVGC series valves have
an adjustable PTFE packing gland for easy
maintenance and longer service life. For
operator safety the BVGC series valves are
ftted with anti-extrusion stems to prevent blow
out and all valves are 100% pressure tested
twice to ensure zero leakage. For other thread
confgurations please consult your Parker
sales engineer.
