This class 800 Sharpe valves 34836 series stainless steel 316L gate valve has an outside stem and yoke, lockable oval handle, and female National Pipe Taper (NPT) threads on both ends. It has a bolted bonnet, and stainless steel 316L construction provides strength and greater ease in welding than stainless steel 304. The lower carbon content of the material minimizes harmful carbide precipitation due to welding, ensuring corrosion resistance. The outside stem and yoke moves up and down with the gate, providing a visual signal (when extended) that the valve is open. The stem, which rises through bushing in the handwheel, is kept out of the flow to avoid corrosion and extend valve life. The outside stem makes it easy to lubricate threads for smoother movement. This valve has female NPT threads on both ends for connecting to male pipes with tighter seals than straight threads. Mounted on top of the valve, a manually operated hand wheel activates the inside screw mechanism, which lifts and lowers the gate to start and stop the flow between the connected pipes. The hand wheel is lockable to prevent the valve from being opened or closed accidentally. This gate valve meets American Society for Testing and Materials (ASTM) A182 standards for quality assurance. Gate valves control flow in a piping system by lifting a gate out of the path of steam, fluids, or gases. They are designed to block or permit flow, as the vibrations and force of flow repeatedly striking a partly lowered gate can damage the gate and seats. To accommodate different flows and pressure requirements, gates come in four types: solid wedge (appropriate for almost all liquid service), flexible wedge (appropriate for steam service), split wedge (appropriate for normal temperature, non-condensing gas and liquid service, including corrosive service), and parallel disc (appropriate for high and low pressure applications). Hand wheels or levers activate the screw mechanism in the val
