Fisher NotchFlo DST Control Valve – High-Performance Valve for Dirty, Cavitating Services from Emerson
The Fisher NotchFlo DST Control Valve is a specialized solution designed to handle demanding flow conditions in industries requiring high durability and performance. Engineered specifically for dirty, cavitating services, this advanced control valve ensures seamless operation even in the most challenging environments. With its innovative trim design, the Fisher NotchFlo DST Control Valve effectively eliminates cavitation while allowing large particulate matter—up to 12.7 mm (1/2 inch) in diameter—to pass through without clogging.
This makes it an ideal choice for industries such as oil and gas, chemical processing, and power generation, where reliability, efficiency, and longevity are crucial. The valve’s rugged construction and cutting-edge design ensure long-term performance while minimizing maintenance and downtime.
Key Features of the Fisher NotchFlo DST Control Valve
- Cavitation Prevention: One of the standout features of this control valve is its ability to prevent cavitation. By using a series of flow restrictions and expansions, the trim effectively dissipates energy, eliminating cavitation before it can cause damage.
- High Pressure Drop Limit: The valve is capable of handling a pressure drop of up to 290 bar (4200 psi), making it suitable for high-pressure applications where standard valves might fail.
- Handles Large Particulates: Unlike conventional control valves, which often clog when exposed to particulate matter, the Fisher NotchFlo DST Control Valve can pass particles up to 12.7 mm (1/2 inch) in diameter, ensuring uninterrupted operation.
- Protected Seat Design: The valve’s shutoff function is separated from the throttling function, preventing excessive wear on the seating surfaces. This unique design significantly extends the valve’s service life.
- Hardened Metal Seats: With durable metal seats, this valve provides a tight shutoff, reducing seat erosion and ensuring reliable operation under harsh conditions.
- Cage-Type Trim: The trim design allows for easy removal and inspection of internal components without the need to remove the valve body from the pipeline, simplifying maintenance and reducing downtime.
Why Choose the Fisher NotchFlo DST Control Valve?
The Fisher NotchFlo DST Control Valve stands out as a superior choice for industries that demand precision, durability, and efficiency. Whether dealing with cavitating liquids or high-pressure drops, this valve ensures optimal performance. Its ability to handle large particulates without clogging makes it a preferred solution for challenging fluid control applications.
