What is the reason for the classification of pneumatic flange vacuum butterfly valve not operating when it is electrified? The second thing to note is the brand of the pneumatic butterfly valve itself. A big brand can often get the trust of users more quickly, but the products without a brand can not find the responsible party once problems occur. Therefore, when purchasing such butterfly valve products, you must choose a well-known brand to purchase.
、 (3) Expansion of flow heat If the butterfly valve works in a closed environment for a long time, the closed chamber in the valve body is likely to have fluid. If the fluid inside cannot be released in time, it will heat up and expand, which will only cause the pressure edge to fail. Even though the products we supply have ball pad pressure, which can be automatically adjusted to prevent the pressure from increasing, we still recommend that you use the pipeline system design or installation, operating procedures to prevent related problems, so as to avoid the pressure in the valve body exceeding the rated pressure.
