NC-930
NC-930 is a spring-loaded safety relief valve with adjustable set pressures up to 120 bar. It is an enlarged version of the NC-230 model, designed to operate at higher pressures while maintaining the same material specifications.
Explanation
NC-930 is a spring-loaded safety relief valve with adjustable set pressures up to 120 bar. It is an enlarged version of the NC-230 model, designed to operate at higher pressures while maintaining the same material specifications.
It is primarily used in gas pressure regulation and measurement stations. Thanks to its compact dimensions, it offers easy installation, and its wear and corrosion resistance makes it ideal for long-term service with reduced maintenance costs.
Its robust design and hygienic compatibility also make it suitable for the food industry and as a component in air compressor systems.
