Parker Metric Ball Valves Series MBVG
Principle
The MBVG series ball valves with their
compact design offer the solution to
applications where space is an important
factor. The body is of a particularly robust
design. The integrity of the sealing on the ball
is obtained by the use of PTFE seats. The
valves are available with BSPP female threads
ISO-228/1 (DIN 299) in : 1/4” & 3/8”.

Technical Features
N.B. This chart gives general information. Only testing under operating conditions will fnally
determine which valve should be selected.
Advantages
Design of the body
The valve is manufactured from a solid section
which incorporates the stem housing in the
body. This design allows excellent guidance of
the stem, which increases its lifespan.
Stem tightness
A Fluorocarbon O-Ring assembled under
compression automatically compensates for
minute friction wear. Thus a high standard of
seal is attained.
Tightness of the seals
The perfect tightness of the seals on the
casing is obtained by the preset force of the
nut, adjusted during assembly.
