SMC Corporation, a global pneumatics manufacturing company with US headquarters in Noblesville, Indiana, has introduced its range of VP544/744-X555/585 dual residual pressure release valves with soft start-up function, designed to meet ISO13849-1 standards for safety.
“In the event of an emergency, most if not all applications will require the release of all stored energy including compressed air,” explains James Graham, Manager of Mechatronics and Control Systems for SMC Australia and New Zealand. “The design of these valves features an integrated soft-start up function that gradually builds the pressure of the pneumatic system, delivering performance consistency and excellent safety.”
The valves have two stations, so if one fails to operate, residual pressure should be released by the remaining valve to maintain the safety function. They also include a selectable throttle and fixed orifice, designed to allow pressure to be adjusted.
