Abstract

PURPOSE: To make a ball valve seat resistance to corrosion, chemicals and heat with sufficient sealing function, by composing the seat with metallic material.
CONSTITUTION: A seat 3, made of metal such as stainless steel and chromium steel, is used together with a screw ring 4. This seat 3 forms an opening 30 toward a clearance between a ball valve body 2 and a setting seat 12 in a valve box 1. A recession 31 with a U-shaped cross section is formed on the seat 3, and the tip of junctures 33, 34 for the setting seat and valve body on both sides of the recession 31 are tapered. A step 32 is also formed on the external circumference of the seat for fitting the screw ring 4.
