The Next Step in Polyurethane Valve Technology

One 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 tested.

IMPROVED
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.

IMPROVED
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 13%.

INCREASED
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 DME.

LESS
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).


Note on compatibility: While Clayton Corp. provides suggestions, samples and technical support to help in component selection, each customer is ultimately responsible for evaluating and approving components for form, fit and function with their particular application.
