AST control valves deliver high performance, durability, and easy maintenance. Ideal for critical industrial applications, the CV-8450 (straight body) and CV-8750 (angle body) series offer robust cage-guided designs that improve flow control and reduce downtime.
These valves include anti-noise, anti-cavitation, and velocity-control trims, built to handle severe service conditions. The quick-change design locks the seat within a drilled cage that also guides the plug through its full stroke, ensuring precise control and plug balancing for lower actuation force.
Their thermal compensation system supports extreme temperatures, from -55 °C (up to -196 °C for cryogenic models) to 566 °C. Multiple plug balancing options provide tight shutoff performance and high sealing classes across all temperature ranges.
Available trims include standard, low-noise, single, and multi-cage types, with flow capacity (Cv) ranging from 0.05 to over 6000. Choose between equal-percentage or linear flow profiles to reduce noise, cavitation, and erosion in any process.
For the most demanding gas and liquid services, the VeCo-LT labyrinth trim ensures multi-path, multi-step control. A pilot plug option supports zero-leakage applications with high-temperature compressible fluids or atmospheric vents.
For flashing or high-differential pressure conditions, AST also offers fixed orifices downstream for full velocity control.
