What is a Safety Valve?
A safety valve is a critical safety device designed to release pressure from a process when it exceeds a predetermined set pressure. The set pressure is maintained by a spring compressed between spring plates. The upper end of the spring plate is locked, allowing the force to act only downward. If the pressure beneath the disc surpasses the spring force, the safety valve opens. The valve recloses when the pressure drops to 10–30% below the set pressure. Therefore, the operating pressure must not be too high.
Safety Valve Selection
We size and select safety valves suitable for our customers’ applications. Please provide the application and process parameters to our sales representative, who will assist in selecting the appropriate safety valve.
We maintain a substantial buffer stock of various body types and springs. For urgent deliveries, we can quickly and reliably set the valves to the desired set pressure. We also offer safety valve maintenance services.
Our product range includes a comprehensive selection of safety valves to meet different process requirements.
The range includes both low-lift and full-lift safety valves, valves with open and closed bonnets, and hoods ranging from open to gas-tight models. This selection ensures suitable models for steam, liquid, and gas applications. Dynamic and/or static backpressure must not exceed 10% of the set pressure. If this cannot be avoided, the safety valve can be equipped with a bellows.
Safety Valves for Steam
In steam processes, full-lift safety valves are typically used, where the inlet flange is two sizes smaller than the outlet flange. This design accounts for the expansion of the medium and provides better capacity. Our product range includes both DIN and ASME standards.
Safety Valves for Process Media
Our range includes small threaded stainless steel safety valves for the process industry, as well as large steam safety valves for high-pressure applications, available in both DIN and ASME standards.
Safety Valves for Liquefied Petroleum Gas and Natural Gas
We offer safety valves suitable for liquefied petroleum gas and natural gas applications.
Safety Valves for Cryogenic Media
Our selection covers safety valves for cryogenic media such as hydrogen, LNG, oxygen, nitrogen, and argon.
The HEROSE cryogenic safety valves we represent are certified according to global CN, TR CU, and ASME certifications. This allows them to be used worldwide, regardless of the final installation location. Cryogenic safety valves are available in sizes DN 6–50 and can withstand pressures up to 550 bar, operating within a temperature range of -270 to +400°C. The safety valves are primarily made of stainless steel, but they can also be manufactured from bronze and brass.
