NC-230
NC-230 is a spring-loaded safety relief valve with adjustable set pressures up to 45 bar. It is primarily used in gas pressure regulation and measurement stations. Thanks to its compact dimensions, it offers easy installation, while its wear and corrosion resistance make it ideal for long-term service with reduced maintenance costs.
Explanation
NC-230 is a spring-loaded safety relief valve with adjustable set pressures up to 45 bar. It is primarily used in gas pressure regulation and measurement stations. Thanks to its compact dimensions, it offers easy installation, while its wear and corrosion resistance make it ideal for long-term service with reduced maintenance costs.
Its dimensional and material advantages also make it suitable for use in the food industry and as part of air compressor systems.
