Next Step in
Polyurethane Valve Technology
of the toughest challenges in valve design is to ensure product performance,
despite occasional mishandling (during transport or storage) after
the product leaves the plant. The Series-900 valves were developed
to do just that, engineered
to be more forgiving while still providing optimal performance.
Series-900 valves have been subjected to tests for chemical resistance, stem strength,
gas permeation, and resistance to sticking in
elevated temperature/humidity settings. They've proven
to be far superior to "standard" valves in all categories
Resistance to Sticking – Series-900
gun valves have lasted more than 2-1/2 times that of standard valves – without
showing any signs of sticking – when subjected to elevated
temperature and humidity settings. The 970 valve (for straw dispensing)
has resisted sticking 50% longer than standard valves. Tests are
ongoing to determine final sticking points.
Chemical Resistance – The
940, 950, and 960 valves have proven to be 38% more resistant to
swell in MDI and 45% more resistant to swell in hydrocarbon/DME
(50/50) than current seals. The seals resist hardening in MDI by
Stem Strength – The
950 and 960 valves have a stem that is 67% stronger in tensile
strength than previously used material. It's more than 80% stronger
after exposure to hydrocarbon, hydrocarbon/DME and straight DME.
The 970 valve has a stem made with a new plastic alloy, making
it more than 50%
stronger after exposure to hydrocarbon, hydrocarbon/DME and straight
Gas Permeation – The
940, 950, and 960 valves reduce gas loss by 40% in hydrocarbon/DME
(compared to current valves). The 970 valve experiences 38% less
gas permeation in hydrocarbon/DME 50/50 (vs. competitive valves).
