As a result, Pneumax products are perfectly suitable to work with sweet gas media and corrosive / aggressive gases. All external and internal parts are AISI 316L stainless steel material in compliance with NACE standard MR0175/ISO 15156-1. The range includes solenoid valves with 3 and 5 ways functions, complete with self feeding solenoids, designed according to the following configuration: solenoid-spring valve, solenoid-solenoid valve, solenoid valve with self-locking manual reset, solenoid valve with self-locking manual reset inverted. Pneumax solenoid valves have 1/4” NPT connections with 1000Nl/min maximum flow rate. Pneumax solenoid valve utmost adaptability represent one of the main features to provide customized solution and module assembly solution, since both single mounting and integrated module design are available; thanks to distinctive Pneumax valve body design.
