SHARPE VALVES. 53034 Series Carbon Steel Ball Valve, Three Piece, Inline, Lockable Lever Handle Package Dimensions ? : ? 5.2 x 2.3 x 1.4 inches; 15.2 ounces Item model number ? : ? SV53034TE002 Date First Available ? : ? May 10, 2012 Manufacturer ? : ? Smith-Cooper International ASIN ? : ? B00835TMJ4 Product Description The Sharpe Valves 53034 series carbon steel three-piece inline ball valve has a lockable lever handle and National Pipe Taper (NPT) male threads on both ends. It has an actuator ready ISO 5211 mounting pad for automation. The valve body is made of carbon steel for strength and greater hardness than stainless steel, and the ball and stem are made of stainless steel 316 for greater corrosion resistance than standard steel. This valve has a lockable lever handle for manual on/off control. Reinforced polytetrafluoroethylene (RPTFE) 15% glass reinforced seats reduce the risk of leakage. The valve is full port for reduced friction; its inner diameter is the same as the inner diameter of the connecting pipe for maximum operating efficiency. This valve has female NPT threads for connecting to male threaded pipes, creating a tighter seal than straight threads. The maximum pressure rating is 1000 pounds per square inch (gauge) (psig) for water, oil, and gas (WOG), and the maximum working temperature is 450 degrees Fahrenheit. 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.
