VSH Press - Pinhol

2.2 Advantages of VSH Press Sprinkler
In the building installation market the advantages of press systems over traditional solutions such
as threading, soldering and welding have long been recognized. The same advantages apply for
VSH Press in sprinkler installations:
• Performance guaranteed
• Reliable
• Easy & clean
• Safe
• Speed
Apart from these advantages, the aesthetics of a VSH Press installation (compared to e.g. black
steel) are often a reason for architects and designers to prescribe our system for in-sight/exposed
installations.

2.2.1 Performance guaranteed
With all fittings being manufactured in our
state-of-the-art factory in the Netherlands,
VSH guarantees consistent quality and
supply. High-tech manufacturing, using laser
welding technology, ensures that all welded
fittings are tested 100%. This leak test is
entirely integrated and automated in the laser
welding process. All straight connectors with
a threaded end and reducers are made out
of one piece, meaning no risk of leakage and
short build-in dimensions.

Performance in flow is obvious, with the extremely smooth surface of tubes and fittings, flow rates
are much better than those in traditional solutions. The performance of our fittings can also be
measured by the various number of national and international approvals. With certificates for
drinking water, in house gas installations and now also sprinkler there is a wide range available of
system and product approvals.
2.2.2 Reliable
In VSH Press Sprinkler systems, the quality
of the connection is mainly determined by the tool and
not the operator, therefore reducing the risk of
installation mistakes. All fittings in the dimensions
DN20-DN50 (22-54mm) are equipped with Leak Before
Pressed (LBP) O-rings, to reduce this risk
even further. This LBP function ensures that fittings,
which have not been pressed, will leak during the initial
pressure test. The installer can immediately see which
fitting he forgot to press and correct this. Once pressed,
the system is guaranteed water and air tight.
