Manatrol FF250CS-99 Manual Steel Needle Valve

The Manatrol FF250CS-99 is a precision manual needle valve designed for fine flow control in industrial hydraulic systems. Manufactured by the Manatrol Division of Parker Hannifin, this carbon steel valve excels in applications requiring accurate regulation of fluid flow, such as in hydraulic circuits, test stands, and process control systems. Its robust construction ensures durability under high-pressure conditions, making it suitable for oil, water, and other compatible fluids in manufacturing, aerospace, and automotive industries. Key features include a T-handle for easy adjustment, female NPT ports for straightforward installation, and a compact design that fits into tight spaces. Advantages over similar products include superior pressure ratings and temperature tolerance, reducing the risk of leaks or failures in demanding environments. However, it may require periodic maintenance to prevent stem wear in abrasive media. Drawbacks include its manual operation, which lacks automation compared to solenoid valves, and potential incompatibility with highly corrosive fluids without additional coatings. Overall, this valve offers reliable performance, high accuracy in flow metering, and cost-effectiveness for both new installations and replacements. Based on image analysis, the unit appears new or unused, stored in an aged original box, with no visible damage or wear on the valve body. No parent/child assets are evident. Estimated market price range: $50-$100 USD for similar used/new surplus units; this listing estimates $75 USD based on condition and comparable sales on industrial surplus sites like eBay and Grainger.
