Large Diameter (11/4,11/2) Air Operated/Series LVC80-Z Manually Operated/Series LVH80M-Z RoHS Low Water Hammer Driving Method Air Operated Driving Method Option With Indicator Light High Back Pressure 0.7MPa Compact design by balance mechanism !Applicable tubing size: 1 1/4", 1 1/2" !Height: 189 mm !Low pilot pressure is achieved: 0.35 to 0.6MPa !Acids and alkaline available !Export Trade Control Order Not applicable for list control As a pressure-balance mechanism with the double diaphragm is used, the spring reaction force that closes the main valve can be made small. This suppresses the height size to achieve the compact design.
