Proprietary Technology
Every Gould solenoid valve features our patented internal piston pilot-operated Velvetrol® mechanism. The design follows a simple engineering principle: fast opening with controlled closing to help reduce water hammer. This inverse relationship provides inherent water hammer protection without external devices, additional cost, or field adjustment.
Unlike conventional ASCO solenoid valves that close at full electromagnetic speed — generating pressure spikes exceeding 6,600 PSI in larger sizes — Velvetrol® valves progressively restrict flow during closure, dissipating kinetic energy through the pilot chamber and reducing hydraulic shock at the source.
