Section 4<br />

Divert Valves<br />

Divert valves for the pharmaceutical and bio-processing<br />

industries are used for converging media from two pipes<br />

into one (W valve), or for diverting media from one pipe<br />

into two pipes (X valve). This divert function is also known<br />

as non-slamming divert.<br />

4<br />

The valve stem has two gaskets, one upper and one lower.<br />

Dependent on the valve status, either one or the other of the<br />

valve seats is shut while the other is fully open.<br />

One seal is always used on the one-part valve disk in order<br />

to shut-off the pipes from each other (upper – central or<br />

lower – central). If the seal fails, the media in the pipes<br />

may intermix.<br />
