Ball valve completes piping system
AGRU, Austria, is a manufacturer of piping systems, including the Agruline
range. To meet growing demands
for uniform PE-pipeline systems, the
company’s supply programme has
been expanded by the PE 100 ball
valve.
The patented PE 100 ball valve with
its simple control mechanism is an
innovative solution for gas, water
and sewage applications, and has a
number of advantages in comparison
to existing valve systems. The
construction of the ball valve is based
on a reinforced inner cage, which
ensures safety and pressure resistance. It is fully coated with PE 100 material
and has a positive fit connection without welding seams. The heavy duty and
redundant sealing-system and three-way centring mechanism of the ball ensure
operational reliability.
The range covers outside diameters from 32 to 225mm. The AGRU ball valve
withstands high operating pressures (16 bar for water, 10 bar for gas) and
features a heavy-duty monobloc construction. Benefits include easy installation
due to lightweight construction and the application of all common welding
technologies, corrosion resistance, and an integrated gearbox that enables
smooth opening and closing.
