The Needle valve for a hand pump is an essential component that controls the flow of fluid in a manual pumping system. It is designed to regulate the amount of fluid being dispensed or pumped by adjusting the size of the flow passage. The needle valve consists of a tapered needle-like plunger that can be adjusted to vary the flow rate, providing precise control over the fluid output.Attributes:• Internal seal made of Nitrile material. • Has a maximum working pressure of 34.5 Mpa.• Resistant to corrosion, wear, and chemical damage, ensuring long-lasting performance.• Provide a tight seal when closed, minimizing fluid leakage• Offers precise metering capabilities, allowing for accurate measurement.• Designed for smooth and low-friction operation.Applications:The Needle valve allows the user to control the flow of fluid with precision by adjusting the position of the needle, the desired flow rate can be easily achieved.
