The Winters SMV series brass mini ball valve has a lever handle, and is made of brass for corrosion resistance, ductility at high temperatures, and low magnetic permeability. Brass can be connected to copper, brass, plastic, aluminum, and welded steel. This valve has a steel lever handle with a plastic sleeve for manual on/off control. Teflon gaskets reduce the risk of leakage. The NPT threads create a tighter seal than straight threads. The maximum operating pressure is 400 pounds per square inch (psi), and working temperature range is -9 to 212 degree 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.

Winters manufactures industrial instrumentation. The company, founded in 1953 and headquartered in Toronto, ON, meets certification standards from Factory Mutual, the Canadian Standards Association, and Underwriters Laboratories along with ISO 9001:2008 and ASME B40.1.
