Ball valve

​2 Piece Spring Return Ball Valve

2 Piece 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. The maximum pressure is 2,000 pounds per square inch (gauge) (psig) for water, oil, and gas (WOG) for 1/4” to 1” valves, 1,500 psig for 1-1/4” to 2” valves, and 150 psig for all sizes for saturated steam. The valve is inline for connecting two pipes going in the same direction and has NPT threads on both ends for creating tighter seals than straight threads. Multifill polytetrafluoroethylene (MPTFE) reinforced seats and stem packing reduce the risk of valve leakage.
