166 Overall dimensions and technical information are provided solely for informative purposes and may be modified without notice Quick exhaust valves Series VSR The quick exhaust valves and the manual valves, 503 series, are produced in Italy according to the reference ISO norms as warranty of high quality level. Quick exhaust valves Series VSR Pneumatic fittings Valves and function fittings Technical characteristics General test conditions and life test: Fluid: Filtered air Temperature: 20 ° C Pressure: 6 bar Tank capacity: 5 liters Test Results The technopolymer valves have the same flow rate as the brass version, the time of pressurization and emptying of the tank is the same. The opening and the exhaust time of the valves do not change by varying the operating temperature, from -20 ° C to +50 ° C. The breakout of the threads, for the technopolymer version, is inversely proportional to the temperature rise. Subjecting the valves to 50,000 charge/discharge continuous cycles, at a constant pressure of 7 bar, the functioning was showing none irregularities.
