Frequently Asked Questions
A silent check valve automatically prevents medium backflow while eliminating water hammer and operational noise in industrial pipelines, protecting pumps and upstream system components.
This valve is designed for operating temperatures between -20°C and 120°C and complies with PN10, PN16, and PN25 pressure ratings.
The built-in buffer spring facilitates a quick and gentle closing mechanism prior to fluid reversal, stopping destructive pressure surges and noise before they develop.
The valve is manufactured in accordance with the API609 standard, utilizing investment casting for precise dimensions and zero-leakage performance.
It is widely used in power plant boiler feed lines, thermal heating circulation, chemical high-temperature piping, and industrial cooling water systems.
All valves are packaged in standard export wooden cases to ensure maximum protection against damage during transit.
