Products/Services for Gas Backflow Preventers

  • Backflow Preventers-Image
    Backflow Preventers - (126 companies)
    Backflow preventers are assemblies with two check valves and two shut-off valves that prevent reverses in process flow. They may also include test cocks for each chamber within the assembly. Backflow preventers have a variety of applications... Search by Specification | Learn More
  • Check Valves-Image
    Check Valves - (1941 companies)
    ...that permit gases and liquids to flow in only one direction, preventing process flow from reversing. They are classified as one-way directional valves. Fluid flow in the desired direction opens the valve, while backflow forces the valve closed... Search by Specification | Learn More
  • Gas Valves-Image
    Gas Valves - (520 companies)
    Description. Gas valves are used to handle and control the flow of gaseous media such as liquefied petroleum and natural gas. They are made of metal or plastic and vary in terms of valve size, pressure rating, number of ports, and flow. Connection... Search by Specification | Learn More

    Blowout Preventers - (35 companies)
    Blowout preventers (BOPs) are specialized valve assemblies that prevent uncontrolled flow of fluid media during well drilling operations. Several assemblies are typically stacked to create a fail-safe mechanism that safeguards the integrity... Learn More
  • Gas Sensors-Image
    Gas Sensors - (571 companies)
    Gas sensors interact with a gas to initiate the measurement of its concentration. The sensor then provides output to an instrument to display the measurements. Image Credit: Rosemount Analytical | Mettler-Toledo Process Analytics. Gas sensors... Search by Specification | Learn More
  • Gas Instruments - (960 companies)
    Image credit: Det-Tronics | Fotronic Corp. | MSA. Gas instruments detect, monitor or analyze gases present in an environment. Detectors sense situations outside normal operating parameters and are set to alarm when these conditions are violated... Search by Specification | Learn More
  • Industrial Valves - (3319 companies)
    Non-return or check valves control the direction of flow. Flow in the desired direction opens the valve, while flow in the oppose direction forces the valve closed. These valves are important for preventing backflow to systems in applications... Search by Specification | Learn More
  • Water Valves - (580 companies)
    ...iecSimulations. Non-return or check valves control the direction of flow. Flow in the desired direction opens the valve, while flow in the oppose direction forces the valve closed. These valves are important for preventing backflow to systems in applications... Search by Specification | Learn More
  • Gas Pressure Regulators - (282 companies)
    Gas pressure regulators reduce the pressure of a gas, as it passes through a cylinder or process line, to another piece of equipment. Regulators are not flow control devices. They are used to control delivery pressure only. Description. Gas pressure... Search by Specification | Learn More
  • Gas Flow Meters - (427 companies)
    Gas flow meters are used for measuring the flow or quantity of a moving gas in an enclosed pipe or passage. How to Select Gas Flow Meters. Image Credit: OMEGA Engineering Inc., Aalborg Instruments, Clark Solutions. Gas flow meters are used... Search by Specification | Learn More
