Selection of control valve for liquid chlorine medium. Thank you
Thread Content
For media such as liquid chlorine and chlorine gas, which type of sealing mechanism should be used for the control valve? And what materials should be chosen for the base, seat, and valve core? Thank you. It turns out that using graphite and PTFE fillers can lead to easy leakage.
Dual sealing with bellows and packing, Hastelloy bellows.
A bellows seal type is required as specified.
A bellows is used for the sealing type. Lined ones are used for valve internals at low pressure. High pressure requires alloy steel. It also depends on whether the medium is gaseous or liquid.
