Series 161 Dry Armature 2 Way Normally Closed Solenoid Valve Ultravalve supplies the Series 161 2 way normally closed direct-acting solenoid valve for automated on/off flow isolation in commercial sweeper equipment and compatible low pressure fluid systems. Featuring a dry armature design with no metal parts in contact with the media, the Series 161 is designed for applications where direct media contact with metallic valve components should be avoided. These valves provide dependable electrically actuated flow isolation for sweeper fluid circuits requiring direct-acting control. Dependable Dry Armature Isolation for Commercial Sweepers Ultravalve’s Midlands based warehouse offers a range of Series 161 valves from stock, subject to configuration and current availability. Designed to support sweeper maintenance projects and OEM equipment integration, these specialised valves help provide fast replacement options for urgent fluid circuit requirements. Dry Armature Design: Features an internal dry armature construction with no metal parts in contact with the media, supporting use with compatible fluids where media isolation from metallic valve components is required. Direct-Acting Performance: The direct-acting mechanism enables reliable on/off flow isolation in compatible low pressure applications. Defined Pressure Handling: Supports a maximum allowable pressure of PS 2 bar. Standard versions list maximum differential pressure of 0.15 bar or 0.5 bar depending on coil/power configuration, while vacuum versions operate down to -0.9 bar, with the lower power DC version listed to -0.7 bar. Acetal Copolymer Construction: Manufactured with an acetal copolymer body, AISI 303 armature tube, AISI 430FR plunger and core, and AISI 302 springs. The construction table lists silicone seal material, with FPM also indicated as a seal code option where specified. Fluid Compatibility Guidance: Suitable for compatible media with maximum fluid viscosity up to 25 cSt, subject to material, pressure, temperature and application compatibility. Flexible Integration: Supplied with a compact Hosetail DN8 connection for integration into compatible flexible pipework and commercial sweeper systems. Environmental Protection: Offers IP65 protection when the electrical connector is fitted and IP00 without connector, using DIN 43650A PG9 connector options. Installation Requirement: Designed for installation with the coil mounted vertically above the valve body. Options: Available with Class H insulation, cable attached, special coil voltages, special coil powers and certified coil options.
