Reduced power consumption Energy Saving Type 2 Port Solenoid Valve Direct Operated Series VXE21/22/23 Series VXED21/22/23 Series VXEZ22/23 Pilot Operated Zero Differential Pressure Type Pilot Operated Built-in energy saving circuit. Electrical consumption reduced by approx. 1/3 during holding compared with a conventional model (New Series VX). Energy-saving Model Conventional Model VXE21: 1.5 W VXE22: 2.3 W VXE23: 3.0 W Series VXE23 Energizing time: 5 hours/ day, 250 days/year New VX21: 4.5 W New VX22: 7.0 W New VX23: 10.5 W Series VX23 Energizing time: 5 hours/ day, 250 days/year Energy-saving model Conventional model 70% Built-in energy saving circuit  Replacement for conventional models (24 DCV, N.C. valve only)  No energy saving effect when the energizing time is 200 ms or less per operation  Coil heat reduction  Interchangeable The mounting dimensions and its basic specifications are equivalent to those of conventional models.  Replaceable coil Possible to change the solenoid coil assembly for the VX2, VXD and VXZ with the energy saving coil type.
