Without connections "A" and "B" nOtE : For the dimension including cartridges see page Accessories - Function fittings Piloting curves Construction characteristics - the combination of this two functions ensures that the downstream pressure is maintained in case of accidental loss of supply pressure and at the same time allows for the air to be directly discharged into the atmosphere without going through the pneumatic circuit. A typical application of this combination is close to or directly assembled onto the actuator connection ports. this allows to keep pressurised the cylinder chamber in case of accidental loss of supply pressure and to quickly discharge the same chamber when the blocking valve is actuated. - the possible combinations are the following: - 90° unidirectional blocking valve + quick exhaust valve - 90° bidirectional blocking valve + quick exhaust valve technical characteristics Fluid Filtered air. no lubrication needed, if applied it shall be continuous Working ports size Max working pressure (bar) Flow rate at 6 bar with Δp=1 (Nl/min) temperature °C Weight (g) Overall dimensions and technical information are provided solely for informative purposes and may be modified without notice 1 D4 = Straight Ø4 See CONNECTIONS LIST 0,5 ÷ 10 285 -5 ÷ +50 51 1 | 365 Air distributiOn M5 30 valve + quick exhaust valve
