About Sharpe Valves 35314 Series Steel Gate Valve, Class

This class 300 Sharpe valves 35314 series steel gate valve has a rising stem and flanged connections on both ends. It has a flexible wedge, fully guided integrated seats, and bolted bonnet, and steel construction provides weldability and greater rust resistance than iron. The rising stem moves up and down with the gate, providing a visual signal (when extended) that the valve is open. This stem design also prevent the stem threads from coming into contact with flow to avoid corrosion to extend valve life. This gate valve is full port for reduced friction; its inner diameter is the same as the inner diameter of the pipe it connects to enable maximum operating efficiency. The maximum working pressure is 285 pounds per square inch (psi), and the working temperature range is -20 to 100 degrees Fahrenheit. This valve has flanged end connections for bolting to compatible-sized pipe flanges. 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. This valve meets the following specifications for quality assurance: American National Standards Institute (ANSI) B16.34, B16.10, B16.5; American Petroleum Institute (API) 600, 598. 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 valve’s bo
