Can steam be passed through the shut-off valve during purging?
Thread Content
RT: The shut-off valve is two-position, either fully open or fully closed.
It is strictly prohibited to pass through instruments such as control valves at the time of initial startup; short-duration purging after normal production stops poses no problem
It’s best to avoid going through the original starting point; other locations can be used instead
It’s best not to go through it; it’s okay for a short time though； Because high steam temperatures over an extended period can affect the sealing performance of the sealant at the membrane head due to the heat
It is best to avoid passing through it; cut-off valves are generally used only in the event of an accident in the system. If impurities remain inside the valve after steam cleaning, it may prevent the valve from closing properly, leading to pressure and material leakage – a serious hazard.
