117 Series


The 117 series are bistable, servo-assisted (also known as  latching, pilot operated) solenoid valves. These offer the benefits of significantly lower cost and power consumption when compared with direct acting valves able to give the same performance in terms of flow rate and maximum operating pressure.  Because they require a minimum pressure to open the diaphragm servo-assisted valves are only suitable for use in situations where the inlet pressure is unlikely to fall below the minimum differential pressure quoted by the maker.  A significant advantage of the 117 series is that for most sizes the ACL series 117 solenoid valves require a minimum differential pressure of only 0.15 bar making them usable in a wide range of fluid control applications.  The 117 series is available with a wide choice of seal materials, the solenoid coil can be fitted with an IP65 DIN connector to provide environmental protection.  As with all servo assisted solenoid valves the need for a small diameter equalisation hole in the diaphragm means that they should be protected by a pre-filter if dirt or rust particles are likely to be present in the media.
