Features
ITM Butterfly valve is much smaller than other valve designs. The result are
saving in materials. less weight, small space requirement, and easy installation
and operation. There are several advantage as follows ;
Advantage of Il Myung butterfly valve
- Light and compact
- Easy maintenance
- Small space
- Smooth & quick operation
- Without flange gasket for installation
- Low cost
- Multi flange
Especially, ITM butterfly valve can combines with JIS10K, ANSI125 & 150,
PN10, PN16 in wafer type(Don't need each spec.'s stock.)
