Why the regulator valve proposed anti-blocking function requirements

Posted on

In the case of dirty media or even clean media, the regulation of debris such as welding slag in the pipe may cause the valve to clog or get stuck. Therefore, the valve should require better anti-blocking function, so that the normal regulation. Anti-blocking is the best flow path of the most simple rotary valve, such as ball valve, butterfly valve, eccentric valve, full-featured ultra-light control valve; flow path complex valve, the upper and lower bushing-oriented valves can easily lead to block cards, such as single Seat valve, double seat valve, sleeve valve and so on. Rotary valve is not only anti-blocking function is good, and leakage is small, allowing the pressure and large, so its use will be more extensive.
