Full-wave rectifier type (AC specification: In Insulation type Class B/H) Improved OFF response Specially constructed to improve the OFF response when operated with a higher viscosity fluid such as oil. Improved durability Service life is extended by the special construction. (compared with current shading coil) Reduced buzz noise Rectified to DC by the full-wave rectifier, resulting in a buzz noise reduction. Reduced apparent power . Class B, N.C. valve 10 VA→7 VA (Size 1) 20 VA→ 9.5 VA (Size 2) 32 VA→12 VA (Size 3) Low-noise construction Specially constructed to reduce the metal noise during operation.

Air Water Oil Steam Page 18 Page 16 Page 14 Page 10 Page 5 For Air For Medium vacuum For Water For Oil For Steam Variations Clearance By providing a bumper and clearance, we reduced the collision sound of the core when ON (when the valve is open). Because of the clearance, when using highly viscous fluids such as oil, the armature does not get stuck and the responsiveness when OFF (when the valve is closed) is improved.
