Accreditation Service） in England. The Logo-type mark atleft has been permitted to use by BVQI at the timemodels are suitable for the device that adds very small
amount of coloring agent to the process in petroleum
reﬁning plant and the very small amount of hydrogen to
charge device in the petrochemical plant.
In particular, model 3306−M of high rangeability, some-obtained the certiﬁcation.

times let one valve control possible where usually twovalves are needed.

2 Excellent controllability at low valve travel
Because the standard ﬂow characteristics is modiﬁed
equal percentage, model 3306−M has excellent controllability at low valve travel.

3 Easy sizing
This catalog is supplied for information purpose only and should not be considered certiﬁed marketability and conformability of this product.

Within the range of Cv value from 0.0005 to 0.4, 15
kinds of Cv value enable you to choose the suitable Cv
value to your service.
□ MOTOYAMA is continuously improving and upgrading its product design, speciﬁcations and /ordimensions.Information included herein is subject to change without notice.

4 Rigid structure
The valve plugs are very thick〔Model 3306−M； 7.9mm（5/16 in）, Model 3306−L； 6.4mm（1/4 in）〕, and thethick plugs make the valve rigid and make it free fromdamage at the time of overhaul of valve.
