compressor safety valve adjustment pricelist

An OSHA COMPRESSED AIR SAFETY SHUT-OFF VALVES should be placed immediately after the air control shut off valve and before the hose on a compressor, and after each discharge port that a hose is connected to.

Before starting the compressor the air control valve should be closed completely. When the compressor unloads, open the air shut off control valve very slowly. Full port ball valves tend to work better than gate or butterfly type valves.

The air shut off control valve must be fully open for the OSHA COMPRESSED AIR SAFETY SHUT-OFF VALVES to work. Some portable air compressor manufacturers recommend start-up with the air control valve slightly open. In this case you may have to close the valve and reopen it slowly to the full open position, or wait for the safety shut-off valve to reset itself.

If the OSHA COMPRESSED AIR SAFETY SHUT-OFF VALVES fails to operate despite meeting all condi-tions, check the hose line for obstructions or a hose mender restricting normal air flow.

• Turn on air supply slowly (to avoid tripping OSHA safety valve). Prior to fully reaching operation conditions, the OSHA COMPRESSED AIR SAFETY SHUT-OFF VALVES should suddenly activate and stop air flow.

• If the OSHA COMPRESSED AIR SAFETY SHUT-OFF VALVE is not activated the unit should be disconnected and the lower flow range OSHA COMPRESSED AIR SAFETY SHUT-OFF VALVES should be used. This means you need to use a different valve with a lower scfm range.

• At temperatures below 40°F ensure that OSHA COMPRESSED AIR SAFETY SHUT-OFF VALVES are not subject to icy conditions which may prevent proper functioning.

Safety valves are an assembly that is mandatory on every breathing air compressor and high pressure compressor. The set pressure of the valve can be adjusted to the final pressure by means of spring force. High-pressure compressors, if not shut off, will continue to generate pressure until some component on the compressor breaks or the drive motor is overloaded. For this reason, breathing air compressors are equipped with two safety devices. The electrical limit switch and the safety valve. Some compressors also have additional safety valves in the piping at each compressor stage. Safety valves are available for the two most used pressure stages 200bar ( 232bar ) and 300bar ( 330bar ) in our online store. In addition to the safety valve, the pressure gauge for displaying the pressure of the compressed gas is an important piece of equipment for high-pressure compressors and breathing air compressors.

1- Because the safety valve may be the only device remaining to protect you from a potentially dangerous situation, it is important that the relief valve is in prime condition.

4- Do not expose safety valves to freezing temperatures if there is a possibility that the safety valve  can come into contact with moisture. Under those circumstances it may freeze solid.

5- A relief valve must be capable of discharging all the air produced by your compressor i.e. if the compressor produces 20 cubic feet per minute (approx. 550 litres per second) at 10 bar then the safety (relief) valve should be capable of exhausting that amount + 10% to atmosphere.
