Our Legacy with Pres-Vac Engineering

Our journey began with a close partnership with Pres-Vac Engineering, the world’s leading manufacturer of high-velocity PV valves. As an appointed service agent for Pres-Vac, we gained extensive technical knowledge and field experience in handling their complete range of PV valves, including the renowned PV-ECO, PV-VOC, and the older 853/854 series.

Even today, we remain highly experienced in servicing Pres-Vac systems and carry genuine spare parts to ensure the continued performance, safety, and regulatory compliance of these critical components.
