Safety Relief Valve
Safety Relief Valve
Maximum pressure developed by a compressor is designed to be regulated by a
control system which senses discharge or tank pressure. In case of an emergency,
such as the failure of a control system to function properly, a positive displacement
compressor system is generally equipped with a safety relief valve.
A safety relief valve is a normally closed valve. The poppet of the safety relief valve
is seated on the valve inlet. A spring holds
the poppet firmly on its seat. Air cannot
pass through the valve until the force of the spring biasing the poppet is overcome.
pass through the valve until the force of the spring biasing the poppet is overcome.
Air pressure at compressor outlet is sensed directly on the bottom of the poppet.
When air pressure is at an undesirably high level, the spring will be compressed, the
poppet will move off its seat, and air will exhaust through the valve.
