VX series now also available with built-in strainer, series VXK21, -22 & -23 (see following pages).
VX is also available in a power saving design, series VXE21, -22 & -23. Contact SMC for details.
■ Power consumption reduced by 2⁄3 ■ Easy to order: VX is replaced with VXE
■ Reduced operating costs ■ Longer life ■ Reduced environmental impact
■ Meets RoHS requirements
This valve series is now available in new versions with technical improvements:
■ Built-in damper for quiet operation and long life ■ Increased ow
performance ■ Fewer seat sizes, which simplies proper valve selection
■ Reduced weight and size
Stainless steel valve bodies are available as an alternative to both the new
and the old versions. Contact SMC for more information.
