How does an OSHA valve work?
OSHA valve is a safety device that shuts off air flow to hose in case of excess pressure. Provides safety to the operator and surroundings. Made of heavy-duty steel. Use with 3/4” diameter hoses and 185-210 cubic feet per minute (CFM) of air pressure.
How does a check valve work on a air compressor?
Located between the compressor and the air receiver tank or main header, a check valve is designed to prevent air from bleeding out of the tank or header and back into the inlet line when a compressor shuts down. Unloader valves, meanwhile, allow air to bleed out of the compressor line to reduce load on startup.
Where is safety valve used?
Safety valves are mainly used in industrial applications to protect against overpressure. This overpressure can lead to dangerous situations, fire, or explosions. Safety valves are often found in: The oil, gas, and petroleum industry.
What is one purpose of shut off valves on the compressor during installation and when servicing?
Shut off valves allow for easier servicing of equipment without affecting the rest of the system by quickly stopping air from reaching part of the application in use. Simple to operate, they can be used in the event of risk to safety, equipment failure or in order to carry out maintenance.
How do you adjust a safety valve?
With a slotted screwdriver, turn the screw in the center of the knob clockwise, until flow can be heard escaping from the internal valve. Slowly turn the screw counterclockwise until the flow from the relief valve stops. Turn the screw an additional 1/8 to 1/4 turn counter-clockwise. Replace the silver cap in the knob.
How do I adjust the safety valve on my Atlas Copco compressor?
Operate the safety valve by unscrewing the knurled cap one or two turns. Retighten the cap. Testing The valve can be tested on a separate compressed air line. If the valve does not open at the pressure marked on the valve, consult Atlas Copco. Warning No adjustments are allowed. Never run the compressor without safety valve.
