About Parker SWB Series Stainless Steel Ball
The Parker SWB series Stainless steel three-piece inline ball valve has a lever handle and National Pipe Taper (NPT) female threads on both ends. The valve body is made of stainless steel for resistance to scaling and corrosion. This valve has a stainless steel and vinyl sleeve lever handle for manual on/off control. Polytetrafluoroethylene (PTFE) seats reduce the risk of leakage. The center section swings out to for replacing seats, seals and the ball without major disruption to the piping system. This valve has female NPT threads for connecting to male threaded pipes, creating a tighter seal than straight threads. The maximum pressure rating is 2500 pounds per square inch (psi), and the working temperature range is -65 to 350 degrees Fahrenheit. This valve meets American Society for Testing and Materials (ASTM) 351 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. Parker Hannifin manufactures electromechanical, hydraulic, and pneumatic motion technologies and systems. The company, founded in 1918 and headquartered in Cleveland, OH, provides fluid handling, filtration, sealing and shielding, climate control, process control, and aerospace technologies.
