Multiple Orifice Valves (MOVs) effectively control flow and pressure in demanding valve applications, where high pressure drops, high velocities, pressure surging, or cavitation may occur. MOVs are available with manual, electrical, pneumatic or hydraulic actuators.

"WaterTamer" high energy dissipation anti-cavitation valve can handle extreme drops in pressure. Cavitation occurs in a fluid under a drastic pressure drop where small vapor cavities form and then collapse or implode. If these implosions contact solid surfaces, the material becomes pitted. Over time, continuous erosion causes severe structural damage to the valve.
