Series XSA Specifications Construction/Operation <> By energizing the coil assembly w, the armature assembly r overcomes the composite force, consisting of the force acting on the valve u due to differential pressure and the reactive force of the spring y, and is adsorbed to the core assembly e, opening the valve u. When energizing of the coil assembly w is canceled, the armature assembly r is separated from the core assembly e by the reactive force of the spring y, closing the valve u. <> o Spacer: A spacer used to raise the body when fastening it onto a flat area. Note 1) The actuation pressure difference indicates the difference between Port P (high pressure side) and Port A (low pressure side). Example) In the case of 0.3 MPa, Port A is a vacuum (1 Torr or less), while Port P can be pressurized to 0.2 MPa {2 kgf/cm2}. Note 2) Reverse pressure potential indicates the pressure which can be applied from Port A when Port P is at atmospheric pressure. Note 3) Indicates case of grommet type electrical entry.
