Specifications
Female threads manufactured in
accordance to DIN 2999/ISO 228.
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 fittings, e.g. Triple-Lok, O-Lok, EO,
and BSPP coned adaptors.
Anti extrusion stem
The BVGL series ball valves are fitted 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 flow
All BVGL series valves are full-flow. This limits
the turbulence created by the passage of fluid
across the valve, minimizing pressure drop.
N.B. This chart gives general
information. Only testing un-
der operating conditions will
finally determine which valve
should be selected.
