Feature and Specification
-
<Feature>
Excellent flow volume control performance
Tight shut/high rangeability is realized by combining disc section for full-shutoff and disc section for low-opening control for the disc.
Also, cavitation is suppressed by installing a pressure chamber to improve anti-noise multi-orifice
Installing a multi hall at the disc section for flow-opening control and the fin section realized flow volume characteristics close to ideal equal percent characteristics for flow volume control
-
< Prevention of erosion by jet flow >
The vulcanized bond seat is suitable for controlling high velocity fluid to reduce erosion due to jet flow.
