Check valves

Check valves, as a non-return valves, are used to protect piping and equipment against reverse flow of the medium. They are installed on pipelines and tank stationary and transport on the lines of industrial, measuring, and in the installation, where we have to prevent the backflow of stream flow. Check valves are designed for: water, steam, oil and other natural liquids and gases, work in marine, and performed by acid-resistant to chemically active agents.

Safety valves protect installations against excessive pressure. An essential part of the installation, which is reliable and durable. Depending on the design of the valve, it can protect the system against volatile or liquid agents. Spring-loaded safety valves may be flanged and threaded. Safety valves are used in all plants with the installation of pressure vessels or Booster, which may have different temperature and pressure.

Globe valves are designed for water, steam, oil and other liquids and gases, and acid-resistant performance to the chemically active agents (acids, bases, salt solutions), the range of concentrations of conditioned behavior of materials used in their construction. Are generally used on installations, refineries, pipelines, general purpose industrial and marine pipelines, used to cut off the flow of refrigerant, and in the execution of the fungus control – to throttle the flow.
