This class 150 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.
