A pneumatically actuated flanged ball valve in 316 or 304 stainless steel, full port, with a rack-and-pinion air actuator mounted directly on the ISO 5211 pad \u2014 no bracket, no coupling, nothing to align.<\/p>\n

The body is two-piece (split body)<\/strong>. That matters when a seat wears out: the body bolts apart and the ball and seats come out, so the valve is rebuilt in place instead of being cut out of the line and thrown away.<\/p>\n

Flange Standard \u2014 Read This Before You Order<\/h2>\n

ASME (American) and JIS (Japanese) flanges are not interchangeable.<\/strong> They have different bolt-circle diameters and different bolt holes. A 4\u2033 JIS 10K flange has a 175 mm bolt circle; a 4\u2033 ASME Class 150 flange has a 190 mm bolt circle. They will not bolt together.<\/p>\n

We build both. Tell us which standard your pipeline uses and we will supply the matching valve.<\/strong><\/p>\n

Two-Piece Body \u2014 Why It Is Worth Knowing<\/h2>\n
