For application of changes1. Main differences
1. Energy saving / Improved flow-rate characteristics (P5 and 6) The max. 45% increased effective area shortens supply and exhaust tim
es.
Resin handle and bonnet are available to reduce the weight.
No air bleed when the handle switches reduces energy consumption.
2. White external color (P7) External color changed from silver to white.
3. Additional variations (P8 and 9) Applicable sizes to the double action type expanded and options added.
4. Specifications and performance (P10) No change from the existing series.
5. Mounting interchangeability (P12 and 13) Mounting (face-to-face) dimensions are interchangeable, but the product
height varies for specific models.
