This is a replacement double-Teflon-coated armature compatible with Parker Series 9 pulse valves and Ideal Vacuum High-Speed Pulsed Solenoid Valves. The armature is a stainless-steel rod that actuates the valve when a magnetic field is induced by the solenoid coil assembly. Abrasion-resistant black Teflon™ double-coated armatures are typically more chemically resistant and have faster, more-consistent actuation times than uncoated armatures.
