Butterfly and obstruc valves
Description
Butterfly valves are used to maintain the unidirectional flow of liquid and to prevent reverse flow of the medium. Reservoir dampers, in turn, are used as control valve or shut-off. Flanged or wafer, with manual or automatic with electric actuator, hydraulic or pneumatic. Provided for a wide range of applications: water, wastewater, steam, gas. Butterfly valves of large diameter flanges are mainly used for water supply and sewerage networks.

safety valves
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.
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.
