About Apollo 70-140 Series Bronze Ball Valve With
The Apollo 70-140 series two-piece inline ball valve with stainless steel 316 ball and stem and 250# (psi) steam trim is made of bronze and has a lever-handle and female National Pipe Taper (NPT) threaded connections on both ends. This valve’s maximum pressure is 250 pounds per square inch (gauge) (psig) for saturated steam and 600 for use with water, oil, and gas (WOG). For resistance to corrosion, this valve is made of bronze and its ball and stem are made of stainless steel 316. It has a zinc-plated steel lever handle with a vinyl sleeve for manual on/off control. 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. This ball valve is standard (or regular) port for reduced valve size and cost and has a working temperature range of -20 to 450 degrees Fahrenheit. This 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 one pipe size smaller than the pipe, resulting in less flow through the valve than through the shaft of the pipe.
