NeuForce Pneumatics distributes a wide range of SERTO products in Australia.
SERTO’s stainless steel check valves have ECE R110 gas approval for use in natural gas applications. This is especially important for the rapidly growing market in natural gas and hydrogen-operated automobiles and fuelling stations.
According to René Glaus, Product Manager at SERTO, their components are in high demand because they are very compact and take less space.
The stainless steel check valves in SERTO’s product offering are ECE R110 approved up to 400 bar.
Natural gas is increasingly being seen as the only viable alternative to fossil fuels as it is not only cheaper than petrol or diesel but also friendlier to the environment with lower carbon emissions. Consequently the market for natural gas and hydrogen-operated automobiles as well as fuelling stations is growing rapidly.
On the downside is the restricted range of these natural gas-powered vehicles with space being at a premium for the fuel tank. When looking to save space and weight, designers are very interested in small and compact components such as the natural gas check valves.
Key features of these stainless steel check valves include:
- Check valves are a wrench size smaller than regular products
- Assembly and disassembly as well as repeated assembly is possible radially
- Double-ferrule mechanism works with a compression ferrule rather than a cutting ring preventing damage to the tube
- Stainless steel construction
- The components are approved for diverse groups within the pressure ratings (PN) of 200, 330 and 400 bar
With ECE R110 approval, products and components for fuel systems with compressed natural gas can be built into motor vehicles and fuelling stations. To get ECE R110 approval testing must be conducted according to ISO 15500 Part 2, 3 and 19.
“Our check valves passed all the tests without any objections,” emphasises Glaus. “And because they were assembled for testing with our stainless steel tube unions on both sides, these are virtually certified as well.”
