Valtek Compressor Anti-Surge Control Valve from Flowserve

Flowserve's Valtek compressor anti-surge control valve offers a revolutionary solution to anti-surge control, combining precise control with superior responsiveness in a simple and reliable all-in-one device.

The valves are designed to overcome the challenge of compressor surge in compressor applications, where poorly controlled compressor surge can lead to equipment failure and unplanned downtime or even major accidents.

Valtek's compressor anti-surge control valve solution protects compressors from catastrophic surge damage by providing fast response, rapid actuation of the valve to open when needed, and precise steady-state positioning under recirculating return conditions.

In addition, Valtek compressor anti-surge control valves are quick and easy to install and commission, as well as simple to maintain.

The integrated FOSS anti-surge valve system provides fast response, high accuracy and reliable anti-surge control through

1. JetFlow pneumatic amplifiers provide high flow rates and fast travel speeds, with proportional pneumatic output characteristics that allow precise control of small opening variations while providing high flow rates when fast action is required.
2. SpiralTrack technology eliminates lengthy feedback linkage configurations to provide reliable electromechanical position feedback to the positioner.
3. High-performance linear piston actuator with built-in quick-closing cushion prevents shock damage to the actuator at the end of a fast stroke.
4. Mark 100SC angle-construction valves utilize a large-volume flow path chamber design to achieve extremely high flow rates. Flow rates can be 51% to 248% higher than comparable anti-surge valves.
5. Advanced Trim designs - MegaStream and Stealth - dramatically reduce noise and vibration, resulting in less system wear and damage and less unplanned downtime.
