The exhaust diameter of the ROSS high-speed manual pressure relief valve is equal to or larger than that of the inlet and outlet sides, allowing for the discharge of residual pressure at one of the fastest speeds in the industry.
Scene content: A machine maintenance technician performing regular machine maintenance during the Golden Week. Following company rules, they search for the residual pressure relief valve to shut off all power energy to the machine, cut off the supply air, and begin exhausting the residual pressure air in the piping. With a typical ball valve, it takes much longer than expected to exhaust all the residual pressure air in the piping. If one approaches the machine with the mindset of "well, as long as it's mostly out, it's fine," the compressed air that is still present may suddenly cause the cylinder to move.
