Meter, Throttle, and Control – With Precision
At Perfect Engineers, we manufacture Flow Control Needle Valves designed for precise regulation of liquid and gas flow in industrial systems. With a graduated needle stem and finely machined seat, these valves are ideal for flow metering, throttling, and speed control applications.
Whether you’re adjusting flow in a pneumatic cylinder, chemical line, or hydraulic actuator, our flow control valves deliver smooth, accurate, and repeatable performance — even under varying pressure conditions.
A Flow Control Needle Valve is a manual valve designed to precisely meter the flow rate of a fluid or gas using a fine-threaded, tapered stem. Unlike on/off valves, this needle design enables incremental adjustment, making it ideal for flow-sensitive applications like chemical dosing, actuator speed control, and analyzer systems.
Best suited for applications where flow rate consistency and regulation are critical over time.
