Sight Feed Valves with Solenoid 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.

Drop feeding can be observed through the glass viewing window in the valve body.  The solid gasket design is used with a sealed pressure system (vented designs are also available), withstanding up to 5 PSI DC and 10 PSI AC inlet to drip nozzle pressure.  The solenoid has a 1/2” NPT thread for connecting with conduit and is powered by 120V/60Hz (please consult factory for additional voltages and frequencies).  This valve features an aluminum alloy body, plated steel components, glass sight, Buna-N seals, and a 1/8" diameter port. The total height of the valve is 3 3/8”.  The total width of the valve with is 3 3/16".

This sight feed valve is suitable for temperatures up to 225° F.
