Servo - normally closed solenoid valves


The ACL E107 series of brass servo-assisted solenoid valves is suitable for use on air, water, light oils, neutral gases and other media compatible with the materials of construction.

Also known as pilot operated valves, servo-assisted solenoid valves offer the benefits of significantly lower cost and power consumption when compared with direct acting solenoid valves of a similar size and specification. 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. For most sizes the ACL series E107 solenoid valves require a minimum differential pressure of only 0.1 bar making them usable in a wide range of fluid control applications. Maximum operating pressure is 10 - 15 bar (depending on size). The 107 series feature an all-metal construction with brass body and stainless steel armature tube. The 107 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. The normally open E207 series offer all the benefits of the normally-closed E107 series but with power to close operation.

As with all servo assisted solenoid valves the need for a small diameter equalisation hole in the diaphragm means that they are susceptible to dirt in the media so if this is likely to be an issue a filter should be fitted before the valve.

N.B. Unless a voltage is stated in the description our brass valves are NOT supplied with coils these will need to be selected separately.
