Sharpe Valves 35116 Series Stainless Steel 316 Gate Valve, Class 150, Rising Stem, Inline, 8″ Flanged

This class 150 Sharpe valves 35116 series stainless steel 316 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 stainless steel 316 construction provides higher strength and greater corrosion resistance than stainless steel 304. Stainless steel 316 is sometimes called “marine-grade stainless steel” due to its resistance to chloride corrosion. The rising stem moves up and down with the gate, providing a visual signal (when extended) that the valve is open. This stem design and the PTFE/graphite internal packing also prevent the stem threads from coming into contact with flow to avoid corrosion to extend valve life. The maximum pressure is 275 pounds per square inch (psi) and the maximum steam pressure is 150 pounds per square inch (psi). 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) 603, 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 bonnet, which comes in various designs, to open and close the gate. Union bonnets are preferable for building service piping, threaded-in (or screw-in) bonnets work well for lighter-duty usage, and bolted body-bonnet connections are used primarily in iron multi-turn valves. Most gate valves have either a rising stem, which moves up and down with the gate, or a non-rising stem, which remains fixed in place. When closed, the gate and its seats form tight planar sealing surfaces, ideal for linear liquid flow. Gate valves are used in air, gas, liquid, and steam applications.

Sharpe Valves manufactures a wide variety of valves, including stainless and carbon steel ball, gate, globe, and check valves. The company, founded in 1986 and headquartered in Chicago, IL, meets International Organization for Standardization (ISO) 9001:2008 standards based on Sharpe’s design and manufacturing of valves.
