Conbraco Check Valves

    check valves
  • (Check valve) A device inserted into a moving liquid stream that allows flow of the stream in only one direction; most often used on the inlet and outlet sides of an HPLC pump.
  • A valve that closes to prevent backward flow of liquid
  • (Check valve) A check valve, clack valve, non-return valve or one-way valve is a mechanical device, a valve, which normally allows fluid (liquid or gas) to flow through it in only one direction.
  • (Check valve) used to provide flow through a pipe in one direction only. When installed between an external filter and the pond, it keeps the dirty water in the filter from flowing back into the pond if power is lost. They are also used to keep an external pump primed if power is lost.

Apollo 61-100 Series Bronze Check Valve, Ball Cone, 1/2" NPT Female
Apollo 61-100 Series Bronze Check Valve, Ball Cone, 1/2" NPT Female
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 one direction. Flow enters through one port and exits through the other, closing when flow reverses or stops. Two common types of check valves are ball cone valves and swing check valves. A ball cone valve utilizes a spring-loaded ball seated against a cone-shaped interior surface to stop the flow of fluid in a forward direction, and a swing check valve has a movable disc on a hinge to block reverse flow. Check valves are rated by their cracking pressure (the minimum upstream pressure required for the valve to operate), and they are used in various water, gas, air, and steam lines.
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.

Apollo 70-100 Series Bronze Ball Valve, Two Piece, Inline, Lever, 1/4" NPT Female
The Apollo 70-100 series two-piece inline ball valve is made of bronze and has a 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 and has a zinc-plated steel lever handle with a vinyl sleeve for manual on/off control. The maximum pressure is 600 pounds per square inch (gauge) (psig) for use with water, oil, and gas (WOG) and 150 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. Polytetrafluoroethylene (PTFE) reinforced seats and seals reduce the risk of valve leakage. This ball valve is standard (or reduced or regular) port for reduced valve size and cost and has a working temperature range of 0 - 500 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. 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.
