Description & Features

Spring Return Ball Valve is made of stainless steel and has a spring-return lever handle and female National Pipe Taper (NPT) threaded connections on both ends. This valve is made of stainless steel for resistance to corrosion and has a stainless steel spring-return handle with a vinyl sleeve for manual on/off control. This valve closes automatically when its spring-return lever is released, ensuring that the valve is open only when an operator is at hand.

● Spring Return Ball Valve is a form of quarter-turn valve which uses a hollow, perforated and pivoting ball to control.

● Flow through it. It is open when the ball's hole is in line with the flow and closed when it is pivoted 90-degrees by the valve handle. The handle lies flat in alignment with the flow when open, and is erpendicular to it when closed, making for easy visual confirmation of the valve's status.

● A reliable valve with Stainless Steel body, PTFE seat and Spring Return Handle.

● A blow-out proof stem and insulated grip, lockable lever handle.
