Excellent visibility in open/closed position and stable closing performance with simple operation!


Features


Easy operation of 90-degree rotation 

The 90-degree operation with the lever handle enables easy opening and closing operation compared with the normal hand wheel type. 

Improved visibility of valve open/close position. 

The 90-degree operation ensures that the open/close status of the valve can be reliably identified by the handle position, even from a distance. 


Prevention of excessive tightening of valve 

Since it is possible to prevent over-tightening when the valve is closed, the diaphragm will not be excessively loaded, and a long service life can be expected. 


Compatible with each unit 

Quick open/close handle type is compatible with all our diaphragm valves, so it is also possible to change the operation method of existing valves.
