High-Performance Motor Drive Butterfly Valves MBV-SDⅡ-AZ Series

Long-life, Low-price, High performance, Versatile running patterns

1. Long-life 1,000,000 cycles
2. Low-price Automatic pressure control is made low-priced
3. High-performance Employs a high-performance stepping motor driver
4. High-functionality Leakage (＊Note.1) , Multi-position control, Auto pressure control Motor position-selected （four-position） Equipped with an ABZO sensor, realizing a battery-less absolute system
If the minimum conductance is required, the specification with valve disc O-ring is also available.(However, it cannot be used as a shut valve.)
5．Minimum Diameter ２０A, Available from NW25 size. Only 20A NW25 size can be used as a shut valve.

Note 1) Leakage specification: No valve seal mechanism

Characteristic

• The series of MBV-SDⅡ-M4-ARJ of the valve which is compatible with the low cost is a motor-driven butterfly valve of conductance control exclusive use without valve disc O-ring.
• A stepping motor made by Oriental Motor is used as the drive source for the valve body.The valve disc can be stopped and hold at fully-closed, fully –open and other any position.
• It is multi-stage and can change the opening area of the valve and can use it in wide uses such as the pressure variableness before and after the constant pressure maintenance in the vacuum chamber and the valve or variableness of the exhaust conductance.
• In addition to fully closed and fully open, it can be stopped at any position of up to 14 positions. Position setting can be easily performed by installing support software on a PC.
• Reproducibility often stops in a set position by sending a signal from a host system of PLC etc.
• By combining the dual automatic pressure control system controller of an option with FPC series, the variegated control including automatic pressure control is attained.
