The Apollo 73A-140 series two piece inline ball valve with stainless steel 316 ball and stem is made of carbon steel has a latch-lock lever handle and female National Pipe Taper (NPT) threaded connections on both ends. This valve is made from carbon steel for greater strength and hardness than stainless steel and has a stainless steel 316 ball and stem for resistance to corrosion. The valve has a zinc phosphate coating for corrosion resistance. It has a stainless steel, latch-lock lever handle with a stainless steel nut and vinyl sleeve for manual on/off control. The maximum pressure is 2,000 pounds per square inch (gauge) (psig) for water, oil, and gas (WOG) for 1/4” to 1” valves, 1,500 for 1-1/4” to 2” valves, and 150 for all valves for saturated steam. The valve is inline for connecting two pipes going in the same direction and has NPT threads on both ends for creating tighter seals than straight threads. Reinforced polytetrafluoroethylene (RPTFE) seats and multifill polytetrafluoroethylene (MPTFE) stem packing reduce the risk of valve leakage and this ball valve is standard (or regular) port for reduced valve size and cost. Maximum temperature is 450 degrees Fahrenheit. This valve is for use with water lines, processing plants, and agricultural applications, is AAR Approved #E999032, NACE compliant, 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.
