Manufactured by ACL srl, the 117 Series comprises a range of brass 2 way latching servo assisted solenoid valves. The bi-stable function is achieved by the use of a polarized permanent magnet energising the coil with a DC current for at least 15ms in the reverse direction of the preceding impulse.
The valve body and cover are produced in brass whilst the armature tube, plunger, core and return springs are produced in stainless steel. For the diaphragm, armature seal ACL offer a choice of seal materials – NBR (Buna, nitrile), FPM (FKM), EPDM and WRAS EPDM (special order). Nitrile provides a cost-effective seal for air and water use, FPM is well suited to vacuum and mineral oil based media while EPDM is suitable for water, hot water and glycol based fluids, EPDM should not be used with oil based liquids.
For most media the 117 series of valves can withstand a maximum allowable pressure of 25 bar**.

Special coil powers
The 117 series of valves can be used with fluids compatible with the materials of construction with a viscosity not exceeding 25cSt (mm ²/s).
Two ranges of ACL's standard coils are used for the 117 series the Type 3 and Type 2. These coils offer a choice of standard direct current and operating voltages from 12V to 48V (DC) and 380V (AC). These coils are designed for continuous duty (100%ED) at the rated maximum ambient temperature.
ACL offer a choice of solenoid coil insulation class - class F coils which allow the valve to be used in an ambient temperature range of between -10°C +55°C and class H coils which increase the maximum allowable ambient temperature to +80°C. These coils are designed to be used according to type with DIN 46244 or DIN 43650A electrical connectors; with the connector fitted they offer IP65 protection and IP00 without connector. For hazardous areas ATEX certified explosion proof coils are available to EExmII (Type 7 - special order).
