In parallel, the ball and seat are subject to stronger forces. This scenario would not represent an issue for a device like a check valve. However, in ball valves, it could bring serious trouble. Why? Because they are central process fixtures that must remain operable, even amid a high differential pressure condition.\u00a0<\/p><p>For valves, a high-pressure setting is synonymous with high operating torque and a larger manual effort. So, when designers work within a high-pressure range, they may end up with calculations for lengthy handles and expensive gear requirements. Appropriately enough, the handle\u2019s design can be bound by standards such as ISO14313 and API 6D. Both provide rules on how to prevent collisions with other piping elements.<\/p><p>One way to decrease the operating torque is by reducing the friction coefficient of the material pair, i.e., using modified plastics (PTFE-filled PEEK). Though the results are not always as majorly significant as needed.\u00a0<\/p><p>Another option is to assess other valve components and take action from the findings. As an idea, look at the stem. Big stem diameters increase the size of the valve\u2019s body, raising operating torque (and costs).\u00a0<\/p><p>The target is to analyze all measures that add protection to the sealing elements. And the effective way to do it is by lowering the operating torque and impact forces. Both are critical to extending the valve\u2019s lifespan, especially in high-pressure conditions.\u00a0<\/p><p>That\u2019s why knowing the types of ball valves is decisive in getting the design

They are similar in functionality but slightly different in design. In the first, the rotary ball is only connected to the seats. In the latter, it is held in the body with a trunnion.<\/span>\n\t\t\t\t\t\t\t\t\t<\/li>\n\t\t\t\t\t\t\t\t<li class=\"elementor-icon-list-item\">\n\t\t\t\t\t\t\t\t\t\t\t<span class=\"elementor-icon-list-icon\">\n\t\t\t\t\t\t\t<i aria-hidden=\"true\" class=\"fas fa-check\"><\/i>\t\t\t\t\t\t<\/span>\n\t\t\t\t\t\t\t\t\t\t<span class=\"elementor-icon-list-text\">Floating ball valves are the most used of the two.

Increasing energy consumption, dwindling natural resources and the ever-stricter legal requirements, forced the industry to rethink and use emission-reducing technology. This is also the case in the field of industrial valves. The requirements for environmentally friendly valves are also a recurring topic in the standardization committees in which I am a member, e.g., in the DIN specialist area of industrial valves, committee NA 003-01-01 AA Basic Standards.

In the 24 years that I have been working in the field of industrial valves, I have dealt with many new requirements for the tightness of valves. Increasing energy consumption, dwindling natural resources and the ever-stricter legal requirements, forced the industry to rethink and use emission-reducing technology. This is also the case in the field of industrial valves. The requirements for environmentally friendly valves are also a recurring topic in the standardization committees in which I am a member, e.g., in the DIN specialist area of industrial valves, committee NA 003-01-01 AA Basic Standards. We also deal with the interpretation and implementation of the new TA-Luft in the area of valves in the VDMA working group \"TA-Luft.\"","sameAs":["http:\/\/www.as-schneider.com"]}]}},"_links":{"self":[{"href":"https:\/\/as-schneider.blog\/wp-json\/wp\/v2\/posts\/1700","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/as-schneider.blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/as-schneider.blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/as-schneider.blog\/wp-json\/wp\/v2\/users\/7"}],"replies":[{"embeddable":true,"href":"https:\/\/as-schneider.blog\/wp-json\/wp\/v2\/comments?post=1700"}],"version-history":[{"count":0,"href":"https:\/\/as-schneider.blog\/wp-json\/wp\/v2\/posts\/1700\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/as-schneider.blog\/wp-json\/wp\/v2\/media\/1706"}],"wp:attachment":[{"href":"https:\/\/as-schneider.blog\/wp-json\/wp\/v2\/media?parent=1700"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/as-schneider.blog\/wp-json\/wp\/v2\/categories?post=1700"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/as-schneider.blog\/wp-json\/wp\/v2\/tags?post=1700"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
