Amflo 235 1/4" NPT Air Flow Throttle Valve

• Controls air flow from near shut off to full flow
• Knurled knob is graduated
• Spring loaded ball and detent hold setting
• Solid brass
• 1/4" NPT Male inlet 1/4" NPT Female outlet

This valve did not fit the application I had. It is not so much a device that controls the flow as it is a brass ball valve. It is difficult to control air flow when rotating the knurreled knob. Also there is no stop position to know that flow is cut off. Instead you can continue to rotate around going from full on to full off and then on again etc.
