PURPOSE:To enhance safety with improved response by closing multiplex quick exhaust valves with their pistons in force balanced condition. CONSTITUTION:The air plumbing outlets 19 placed on the specified number of the quick release valve 8, arranged on the external part of the cylinder chamber B of the clutch brake 2 for a press are connected to the distributing box 10 respectively by the piping 9. The cylinder chamber B of the clutch brake 2 is charged and discharged with compressed air via a magnetic switching valve 12 and main piping 11 connected to the compressed air source 13. The distributing box 10 is connected to a position of the main piping 11 near the magnetic switching valve 12 by the piping 14. The air plumbing outlet 19 is installed on the chamber C formed by the piston 15 in the cylinder of the quick release valve 8, and multiplex outlets 17 opening to the atmosphere are installed on a chamber communicating with the cylinder chamber B. Normally, the piston 15 is pressed onto the seal surface 18 to close the exhaust port 17.
