About Apollo 70-100 Series Bronze Ball Valve With
The Apollo 70-100 series bronze two-piece inline ball valve with automatic drain has a lever handle and female National Pipe Taper (NPT) threaded connections on both ends. This valve is made of bronze for higher strength and corrosion resistance than brass. It is primarily for use in pneumatic applications; it has an automatic drain for releasing air pressure from the pneumatic system or tool to which it is connected. When the valve is in the on position, the drain vent is closed off; when the valve is in the off position, air from the downstream system is vented to the atmosphere. This valve has a zinc-plated steel lever handle with a vinyl sleeve for manual on/off control. Reinforced polytetrafluoroethylene (RPTFE) seats reduce the possibility of leakage. The valve is standard (or regular) port for reduced valve size and cost. It has National Pipe Taper (NPT) threads for creating tighter seals than straight threads. The maximum pressure ratings are 600 pounds per square inch (gauge) (psig) for use with water, oil, and gas (WOG) and 150 psig for saturated steam, and the temperature range is -20 to 450 degrees Fahrenheit. This ball valve is for use in water lines, processing plants, and agricultural applications and meets standard MSS SP-110 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 on
