HEROSE is a German valve manufacturer from Bad Oldesloe that has been making valves since 1873. Today it focuses mainly on safety valves and valves for cryogenics and pressure vessel construction, and delivers its products to more than 80 countries. HEROSE has an authorised service partner in the Czech Republic.
A safety valve opens as soon as the pressure in a vessel or pipeline exceeds the set value, and releases the excess medium. We offer valves for compressed air, steam, water and cryogenic gases, with 1/4″ to 2″ threads and with DN15 to DN100 flanges. Every valve is delivered set to your pressure and sealed.
Set and sealedWhich safety valve for which medium
06C02 — compact valve for air
For compressors and air receivers. Brass or stainless steel valve with male thread and open discharge for air and inert gases.
- 1/4″ to 1″ thread
- set pressure 0.2 to 50 bar depending on size
- TÜV-SV.1090 type approval
6217 — full-lift valve for air
High air flow rates. Brass valve for pipelines and pressure vessels that need to release a lot of air.
- 1/2″ to 2″ thread
- set pressure 0.2 to 30 bar depending on size
- temperature −40 to +200 °C
Steam and water: 6380, 6395 and 6370
Steam lines and pressure vessels. Bronze valves 6380 and 6395 for saturated steam, and the 6370 gunmetal valve for water, oil and diesel.
- 6380: steam up to +185 °C, 1 to 16 bar
- 6395: steam up to +225 °C, metal seat
- 6370: water, oil and diesel, 1 to 16 bar
Stainless steel for cryogenic gases
Types 6383, 06012 and 06016. Stainless steel valves for air gases, vapours and liquefied cryogenic gases including LNG.
- work from as low as −196 °C
- set pressure up to 55 bar
- 1/4″ to 1 1/2″ thread
Flanged 6121 and 6127
Large bores and flow rates. The cast iron 6121 for non-aggressive media and the stainless 6127 also for aggressive media and cryogenics.
- 6121: DN15 to DN100, 0.2 to 16 bar
- 6127: DN20 to DN80, 0.2 to 40 bar
- flanges to EN 1092-1

The set pressure range depends on the valve size. Exact values and the flow table are on the page of each valve.
How to choose a safety valve
1. Medium and temperature
Air, steam, water or a cryogenic gas? Choose the type and material by medium and temperature: brass, bronze, cast iron or stainless steel.
2. Set pressure
The valve is set to the pressure at which it opens. It must be above the compressor cut-out pressure and must not exceed the maximum allowable pressure of the vessel.
3. Flow and connection
The valve must release more than the compressor or other source delivers. The capacity for each set pressure is in the flow table on the valve page.
4. Order with the pressure
State the required set pressure with your order. We set the valve in 0.1 bar steps, seal it and enclose the setting report.
Frequently asked questions
- Are the valves delivered pre-set?
- Yes. We deliver HEROSE safety valves only set to the required pressure in 0.1 bar steps, sealed and with a setting report. Please state the pressure with your order.
- What is the difference between the 06C02 and the 6217?
- The 06C02 is a compact valve with open discharge for compressors and smaller vessels, with threads up to 1″. The 6217 is a full-lift valve with threads up to 2″ that releases more air, so it suits pipelines and large vessels.
- Which valve for steam?
- For saturated steam there are the bronze valves 6380 up to +185 °C and 6395 up to +225 °C. The 6370 gunmetal valve is intended for water, oil and diesel.
- What certifications do the valves have?
- The valves comply with the Pressure Equipment Directive (PED) and have TÜV type approvals, for example TÜV-SV.1090 for the 06C02 or TÜV-SV.1048 for the stainless 06012 and 06016. The manufacturer is ISO 9001 certified.
- How much air does a valve release?
- It depends on the size and set pressure. For example, the 06C02 1″ releases 1,261 Nm³/h of air at 10 bar. The flow table for all pressures is on the page of each valve.
- Where does the HEROSE brand come from?
- The company has been making valves since 1873, at first for shipbuilding. Industrial valves followed in 1921 under the name HERO Armaturen in Bad Oldesloe. The name HEROSE was created after 1947 through the merger with the Hamburg company TH. ROSE.
Every valve comes with a setting report. For the 06C02 series, a type sheet, operating instructions and a declaration of conformity in Czech are available for download; for the other types, catalogue sheets.
