The Apollo 70-100 series two-piece inline ball valve with an automatic drain is made of bronze and has a latch-lock 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. This valve is primarily for use in pneumatic applications; it has an automatic drain for releasing air pressure from the pneumatic system 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 ball valve has a stainless steel latch-lock lever handle with a stainless steel nut and a vinyl sleeve for manual on/off control. The lever handle can be locked in either the open or closed position. The pounds per square inch (gauge) (psig) rating for this valve is 600 for water, oil, and gas (WOG) and 150 for saturated steam. It 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 and air applications only 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. 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.
Apollo manufactures ball, mixing, and relief valves, actuators, water gauges, marine fittings, heating and plumbing products, and backflow prevention devices. The company, founded in 1928 and headquartered in Matthews, NC, meets International Organization for Standardization ISO/IEC 17025:2005 and makes products that meet ISO and American National Standards Institute (ANSI) standards.
