ASTM A217 C12A API Pressure Seal Gate Valve<\/a><\/mark><\/strong><\/h2>\n\n\n\n

Pressure seal gate valves are used for high-pressure service, typically for pressures above 100 bar. The unique feature of the pressure seal bonnet is that the body-bonnet joints seal improves as the internal pressure within the valve increases.<\/span><\/p>\n\n\n\n
