Characterized Insert Control Valves The CV3000 Series can be fitted with a wide range of v-style inserts for precision throttling control. The inserts are paced in a machined groove in the end cap behind the upstream seat to characterize the flow. The v-style insert is placed on the inlet side of the valve to protect the seat from high velocities, which can occur while controlling flow. The ball sits between two soft seats, ensuring low torque with a bubble-tight shut off. The insert is designed to change flow characteristics of the valve and is offered in different configurations to meet a variety of modulating applications. |
