Apollo 61-100 Series Bronze Check Valve, Ball Cone, 1" NPT Female

Key features

• Ball cone check valve restricts flow to one direction, blocking reverse flow
• Valve body made of ASTM B-584 bronze for strength and corrosion resistance
• 400 pounds per square inch (gauge) (psig) rating for cold working pressure (CWP) and 125 for steam working pressure (SWP)
• Cracking pressure of 0.5 pounds psi
• Female National Pipe Taper (NPT) threads on both ends for connecting to male threaded pipes

The Apollo 61-100 series bronze ball cone check valve with female National Pipe Taper (NPT) threads on both ends is a class 125 valve used for restricting flow to one direction. It has a spring-loaded ball cone that sits against the seat of the valve to block reverse flow. The check valve's body is made of American Society of Testing and Materials (ASTM) B-584 bronze for strength and corrosion resistance. This valve has maximum pressure ratings of 400 pounds per square inch (gauge) (psig) for cold working pressure (CWP)and 125 psig for steam working pressure (SWP), and a cracking pressure of 0.5 pounds psi. It has female NPT threads on both ends for connecting to male threaded pipes with tighter seals than straight threads. This class 125 check valve is for use in water lines, processing plants, and agricultural applications and meets standard Manufacturers Standardization Society (MSS) SP-80 for quality assurance. Class is a standard relating to tolerance, construction, dimension, and wall thickness, but it is not a direct measurement of maximum working pressure. Check valves have two ports and restrict the flow of fluids and other loose materials through a pipe or passageway to o
