DBM
Operating Instructions
1. Intended use
Pressure limiting valves for compressed air, gases or fluids for reducing briefly occurring
pressure surges or to prevent an impermissible high pressure increase in the system.
Pressure limiting valves cannot be used as flow rate regulating elements or stop valves.
The pressure limiting valves of the series DBM are a type of compact spring-loaded pressure limiter.
The general function of a pressure limiter is described in the following film.

2. Information on the usage instructions
Any handling of the device is under the condition that these usage instructions are understood and followed. The
device is intended only for the application described.
2.1 Symbols
This symbol points out special information or mandatory or prohibited actions to prevent damage.
These instructions serve the purpose of occupational safety!
This symbol is placed next to important instructions, for observing regulations or if there is a
risk of material damage.
3. Safety
3.1 Safety information
Do not endanger yourself or others. Read the following safety information before you
install, operate or repair fixtures.
They serve to avoid danger to persons and the plant. The handling of technical gases – in
particular flammable, self-igniting or toxic gases – requires expertise, the observation of these usage instructions
and special safety measures. Additionally, any relevant regulations and guidelines must be observed. (see 3.2)
Use the fixtures only as intended (see section "Intended use"). The same is valid for the medium used with them:
Improper usage can damage the system or even lead to injuries which could be fatal.
Employ gas monitoring devices if you are handling dangerous gases. These monitoring products detect leaks and
warn personnel.
Wear respirator mask, safety goggles as well as safety gloves if you work with toxic gases and ensure good
ventilation. Make sure that exhaust openings cannot be plugged up and that toxic gases can be exhausted on
fixtures and plants accordingly with venting valves. Some gases can displace oxygen from the air and cause
suffocation. Make sure you have good ventilation when using such gases. It is quite recommendable to install
detectors that emit an alarm in case of a lack of oxygen at the workplace.
DBM Pressure limiting valve
Oils and greases must never be used on gas regulating systems. They can ignite easily and react violently with
some pressurised gases. In special cases, lubricants can be used that are suited then for the respective
application. Implementing AirCom pressure limiting valves in oxygen applications is only permitted with
appropriately marked devices.
