ST-4™ Stacked Disc Anti Cavitation Trim

Email A Colleague

ST-4 Stacked Disc trim is a powerful solution designed to tackle the most severe pressure drops while reducing sound levels and eliminating the effects of cavitation. It can be used in liquid, gas, or dual-phase service. The ST-4 design consists of individual discs machined with concentric channels machined to create a tortuous path and stacked to create a compact cylinder. The cylinder is then clamped into the body cavity of an OpGL globe valve and doubles as a seat retainer.
