79003 Series Angle Style with VRT Trim

The 79003 Series valves offers anti-cavitation service with control over a wide range of operating conditions, such as the ramp-up
transition of a normal feedwater pump.

The 79003 Series is an angle body design developed to use the Variable Resistance Trim (VRT*) for high-pressure liquid letdown applications.

The anti-cavitation VRT trim can be configured to match pump flow curves, allowing steady operation as the plant is brought up to speed and comes on line. The 79003 Series can be enhanced with a partial-stack design to allow higher flow rates as the travel is increased.
