High-Performance CSV Series Safety Valves

The CSV Series safety valves are designed for high-quality performance and precision, making them ideal for steam boilers, pressure vessels, and both industrial and marine applications.

These valves operate with minimal overpressure, allowing precise control even when multiple valves are installed on the same boiler with different set pressures. By staying within the 10% overpressure limit required by regulations, the CSV valves ensure that only the necessary valves open during operation, optimizing system efficiency.

They are also approved by the Italian standard institute ISPESL, guaranteeing high safety and performance standards.

Efficient Pressure Control for Various Fluids

The CSV valves excel in managing both compressible fluids and liquids.

For compressible fluids, such as steam and gas, the valves open quickly when pressure exceeds the set point, facilitating rapid discharge with minimal pressure increase—a feature known as "pop action." This ensures efficient pressure management.

For liquids, the valves operate more gradually, with larger overpressure and blowdown values, allowing for smooth and effective pressure regulation. Their minimal blowdown also helps keep the working pressure close to the set pressure, maintaining system efficiency and quickly restoring normal conditions.
