Advantages
Threaded Exhaust
BVGPLOCK series ball valves are
manufactured with an exhaust port, this
safety feature enables the downstream
air pressure to be vented when the
valve is closed. 1/4-1" have M5 thread.
1.1/4
and larger are not threaded.
Lockable Handle
The BVGPLOCK series ball valves are
fitted 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. Sizes 1.1/4 and larger can be locked
in both the open and closed positions.
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 fittings and EO-
fittings form “A” or “C” to DIN 3852.
Anti Extrusion Stem
The BVGPLOCK series ball valves are
fitted with an anti-extrusion stem to prevent
blow out in the case of pressure peaks.
Full Flow
All BVGPLOCK series valves are full-
flow. This limits the turbulence created
by the passage of fluid 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.
