Advantages
Threaded Exhaust
BVGPLOCK series ball valves are
manufactured with an M5 threaded exhaust
port, this safety feature enables the
downstream air pressure to be vented when
the valve is closed.
Lockable Handle
The BVGPLOCK series ball valves are ftted
with a handle that can be locked in the closed
position with a padlock. This safety feature
ensures the valve cannot be accidentally
opened, and only authorized personnel can
operate the valve.
DIN 2999 / ISO 228 Female
Threads
BVGPLOCK series valves are manufactured
with long female threads in accordance to
DIN2999/ISO228. This enables the valves to
be used with Prestolok, Metrulok and brass
adaptors but also Parker’s range of steel
hydraulic fttings and EO-fttings form “A” or
“C” to DIN 3852.
Anti Extrusion Stem
The BVGPLOCK series ball valves are ftted
with an anti-extrusion stem to prevent blow out
in the case of pressure peaks.
Full Flow
All BVGPLOCK series valves are full-fow. This
limits the turbulence created by the passage
of fuid across the valve, minimizing pressure
drop.
Adjustable Packing
The PTFE packing gland and adjustable
washer are designed to give longer service
like and lower operating torques.
