DELTA

Minimizes noise and eliminates the damage effects of cavitation

The Delta Trim ability to minimize noise and eliminate the damaging effects of cavitation makes in the ValtekSul control valves an effective choice for gas and liquid processes with high pressure drop conditions. Delta trim has confirmed its ability to reduce noise

and eliminate cavitation.

ALPHA

Is a cost-effective trim that minimizes
cavitation damage

The Alpha Trim utilizes a number of

small diametrically opposed flow holes through the walls of a special seat retainer.The flow capacity and characteristics are determined by

size and spacing of the holes in the

seat retainer.
