Parker Metric Ball Valves Series BVGL
Principle
Parker BVGL series valves are designed
for use in fuid and gas applications and are
DVGW approved. The valve dimensions are in
accordance with DIN3357 for interchange-ability
and are available with BSPP female/female*
long threads to DIN 2999 / ISO228. These full
fow ball valves have a chrome plated ball with
a double PTFE seal system 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. BVGL series valves are ftted with
an anti-extrusion stem with two Fluorocarbon
seals for maximum safety and performance.
After assembly all valves are 100% pressure
tested twice to ensure zero leakage. For other
thread confgurations please consult us.

Technical Features
N.B. This chart gives general information. Only testing under operating conditions will fnally
determine which valve should be selected.
Advantages
Long female threads
BVGL series valves are manufactured with
long female threads in accordance to DIN
2999/ISO 228. This enables the valves to be
used with Prestolok, Metru-Lok and brass
adaptors but also Parker’s range of steel
hydraulic fttings, e.g. Triple-Lok, O-Lok, EO,
and BSPP coned adaptors.
Anti extrusion stem
The BVGL series ball valves are ftted with an
anti extrusion stem to prevent blow out in the
case of pressure peaks. The stem is sealed
with two Fluorocarbon O-rings for maximum
safety and performance.
Full fow
All BVGL series valves are full-fow. This limits
the turbulence created by the passage of fuid
across the valve, minimizing pressure drop.
