GAMMA
Cavitation in liquids
Gamma Trim prevents cavitation from forming and minimizes hydro-dynamic
noise even under the most severe liquid applications. In the cartridge Gamma each stage is designed with a series of expansion holes and intersecting circunferential channels that restrict the flow.

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.
