JMI-J JIS B2031 5K/10K Metal Seated Flanged Globe Valves

The opening and a closing disc of the Japanese standard is a plug-shaped flap, the Sealing surface is flat or cone, the valve disc moves straight along the centerline of the fluid. Japanese standard globe valve is only applicable to fully open and fully closed, and no adjustment and throttling are allowed. Japanese standard globe valve is mandatory sealed valves so that when the valve closed, pressure must be applied to the flap, to force the sealing surface free from leakage.


The design standard for the Japanese standard cast iron globe valve is JIS B2031, common pressure is 5K and 10K.
