The Sharpe Valves 58876 series stainless steel 316 unibody inline ball valve has a lever handle and National Pipe Taper (NPT) male threads on both ends. This valve body is made of stainless steel 316 for 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. This valve has a stainless steel lockable lever handle for manual on/off control. Polytetrafluoroethylene (PTFE) seats reduce the risk of leakage. The valve is standard (or regular) port for reduced valve size and cost. This valve has female NPT threads for connecting to male threaded pipes, creating a tighter seal than straight threads. The maximum pressure rating is 800 pounds per square inch (gauge) (psig) for water, oil, and gas (WOG), 150 psig for working steam pressure (WSP), and the maximum working temperature is 450 degrees Fahrenheit. This valve meets American Society for Testing and Materials (ASTM) A351 standards for quality assurance.
Ball valves use a spherical disc to control the flow between pipes, tubes, or hoses. Flow is allowed when the hole that pierces the ball-shaped disc is in line with the inlet and outlet of the valve. Flow is blocked when the ball is horizontally swiveled 90 degrees, so that the hole of the ball is perpendicular to the opening of the valve. Ball valves can be referred to as full port or reduced port (also known as regular or standard port) depending on the inner diameter of the valve. A ball valve is full port if the hole of the ball is the same size as the inner diameter of the connecting pipeline (resulting in lower friction) and is reduced port if the hole of the valve is one pipe size smaller than the pipe, resulting in less flow through the valve than through the shaft of the pipe. Ball valves may have a handle or lever that aligns with the ball's position (open or closed) for manual operation. They are primarily 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.
