American Standard Carbon Steel Gate Valve with Flange Connection

Product DescriptionThe gate of Z40H gate valve is a wedge-shaped elastic gate, and there is a groove between the two layers of sealing rings of the gate, so that the sealing ring of the gate can be elastically deformed. Avoid the overload of the sealing surface caused by the extension of the valve stem due to the high temperature of the gate, the wedge between the gate and the valve seat and the valve can not be opened. So Z40H is more suitable for high temperature medium.Product Parameters Certifications Packaging & Shipping Company ProfileOverseas Exhibition   /* March 10, 2023 17:59:20 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
