Ball Type Drain Valve

Ball Type Drain Valve is ideal for replacing air compressor drain cocks. It is designed with high quality, O-ring free construction for long, trouble-free life. It features pre-applied thread sealant for airtight connections - this simplifies field installation by eliminating the need for thread sealant tape.

The Boss series brass inline mini ball valve has a lever handle and National Pipe Taper (NPT) female threads on both ends. This valve body 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 lever handle for manual on/off control. Polytetrafluoroethylene (PTFE) 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 pipe it connects to 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 600 pounds per square inch (gauge) (psig) for water, oil, and gas (WOG), and 150 psig for working steam pressure (WSP). 



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.
