About Precision Flow-Adjustment Valves
More
Easy-Set Threaded Plastic Precision Threaded Flow-Adjustment Valves
- Valve Type: Needle
- For Use With: Air, Oxygen
- Seal Material: Buna-N Rubber
To ensure consistent and repeatable settings, these valves have color-coded handle threads and numerical markings. One full revolution of the handle reveals a new color to indicate the set point. Turn the handle to adjust flow in small increments for metering, sampling, and other applications requiring fine flow control. The locking knob handle has a ring that prevents accidental adjustment.
Internal check valves actuate when the pressure changes to stop flow control from the controlled direction and allow free flow in the opposite direction. Valves with an internal check valve are often used to control the speed of air cylinders and air-powered motors.
Flow coefficient (Cv) is a measurement that indicates how much airflow can pass through a valve.
