ST-1™ Single Stage Anti Cavitation Trim

Email A Colleague

Trimteck’s ST-1 is a cost-effective single-stage globe valve trim that minimizes cavitation damage to valve piping by diverting the location and controlling the concentration of imploding vapor bubbles to an area away from critical parts. The ST-1 trim works with diametrically opposed drilled, stepped holes that force vapor jets to impinge on each other in a column at the center of the valve gallery rather than erode the valve body or trim.
