Adjustable Sight Feed Valves with Toggle Shutoff

Sight Feed Valves with Toggle Shutoffs allow visual observation of the liquid stream. An adjustable precision needle valve controls the flow rate; it has a friction lock to guard against loosening from vibration. The flow rate can be adjusted from an extremely low drop rate to a stream. These valves are especially useful when small quantities of liquid are needed. Their use can be extended to any application requiring adjustable, visible flow control.
