About Apollo 70-300 Series Bronze Ball Valve, Two
The Apollo 70-300 series bronze two-piece inline ball valve has a lever handle and National Pipe Taper (NPT) female threads on one end and union NPT female end on the other. The valve body is made of bronze for higher strength and corrosion resistance than brass. This valve has a zinc-plated steel lever handle with a vinyl sleeve for manual on/off control. Reinforced polytetrafluoroethylene (RPTFE) seats and stem packing reduce the risk of leakage. The valve is standard (or regular) port for reduced valve size and cost. Female NPT threads connect this valve to male threaded pipes, creating a tighter seal than straight threads. Union end allows simple connection and disconnection. The maximum pressure rating is 600 pounds per square inch (gauge) (psig) for cold working pressure (CWP), 150 psig for saturated steam, and the maximum vacuum pressure is 29 in Hg. The maximum working temperature is 500 degrees Fahrenheit. This valve meets Manufacturers Standardization Society (MSS) SP-110 and WW-V-35C standards 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. Ball valves may have a handle or lever that aligns with the ball's position (open or closed) for manual operation. They are primari
