TigerTooth uses multi-stage pressure drops to eliminate cavitation in liquid services.

 

Valtek Cavitation Control ValvesCavitation Solution Control Valves

ChannelStream

ChannelStream trim prevents cavitation from forming and minimizes hydrodynamic noise even in the most challenging liquid applications. Staged pressure drops eliminate cavitation by maintaining pressure above the vapor pressure—never allowing cavitation to form.

CavControl

CavControl valve trim lowers cavitation damage by controlling the location and concentration of cavitation vapor bubble implosions in an area away from metal parts. CavControl trim utilizes a number of small, diametrically opposed flow holes through the walls of a special seat retainer.

CavStream

CavStream valve trim lowers cavitation damage by controlling the location and concentration of cavitation vapor bubble implosion in an area away from metal parts. CavStream trim utilizes a number of small, diametrically opposed flow holes through the walls of a special plug

DiamondBack

DiamondBack trim prevents cavitation from forming and minimizes hydrodynamic noise even in the most challenging liquid applications. Staged pressure drops eliminate cavitation by maintaining pressure above the vapor pressure, never allowing cavitation to form. DiamondBack combines new advances in pressure drop management with previously proven technologies to create the most effective device capable of eliminating cavitation in the most demanding services.

Sidewinder

SideWinder trim prevents cavitation from forming and minimizes hydrodynamic noise in high pressure drop, low flow applications.  Staged pressure drops eliminate cavitation by maintaining pressure above the vapor pressure, so that cavitation never forms. Using the proven DiamondBack advanced pressure drop mechanisms in an axial flow configuration producing precise control in low flow conditions.

StarPac 3
