2.6 Safety regulations with respect to the operation of the system
• Make a risk assessment of the procedure before you start work (EN-ISO 12100).
• Keep bystanders at a distance and be extra careful in the vicinity of people and animals.
• Make sure the work area is clearly laid out and has good lighting.
• Avoid stress and work in a structured way. This reduces the risk of errors, combinations of dangers
and accidents.
• Before use, check the equipment for damage. Do not use the equipment if it is not in good
condition, and consult your Holmatro dealer.
• Stand on a stable base and use both hands to hold the equipment.
• During operation, never get between the object and the equipment.
• Monitor the situation of the equipment and the structure continuously while using the equipment.
• Never couple or uncouple couplers while the system is under pressure.
• Use only genuine Holmatro accessories and ensure that they have been attached correctly.
• Stop immediately if the system makes strange noises or displays aberrant behaviour.
• Always use a pressure gauge to monitor the pressure in the system.
• Do not lift unstable loads.
• Take extra care when lowering a load.
• Return inactive equipment immediately to the tool station.
• Oil and grease is explosive in the vicinity of compressed air. Do not connect pneumatic tools if any
oil or grease is present. Have the pneumatic tool cleaned by a Holmatro Certified Technician.
• Always adhere to the safety regulations that apply to other equipment that is used in the operation.
2.7 Safety regulations with respect to maintenance
• Wear personal means of protection when performing maintenance tasks.
• Never work in a way that could jeopardize safety.
• Make sure that the equipment cannot roll away or tip over. The control and drive must be switched
off and safeguarded against unexpected activation.
• Make sure that moving parts do not move unexpectedly.
• Used or leaked fluids, and any other products consumed during the activities, must be collected and
disposed of in a environmentally responsible way.
3 Description
3.1 Equipment
The PRV pressure regulator is used with compressed air bottles. Compressed air bottles are used in
many applications, such as Holmatro lifting bags, flow stoppers, leak seals and PowerShore™. The
PRV pressure regulator is suitable for reducing high air pressure in a compressed air bottle. The PRV
reduces an air pressure (P1) of 300 bar / 30 MPa to a much lower air pressure (P2) which is as constant
as possible even if the flow varies.
