Control valves, shut-off valves and Fail-safe action valves
Control valves are the valves used to control flow and pressure of the passing medium. The three-way design are used for mixing or diverting of passing medium.
Shut-off valves are used to shut off pipelines under all normal operating and non-operating conditions. If equipped with electric or pneumatic actuators, its use is in automatic operation. Fail-safe action valves are control or shut-off valves equipped with actuators with safety function, which ensure closing of the valve upon power failure.
In the range of LDM valves occupy the mentioned valves largest amount of products. Available in pressure classes from PN 6 to PN 500, includes a range of nominal sizes DN 15 to DN 400. Execution of two-way valves can be direct or angle, possibly with an extended outlet socket. Three-way control valves are generally dimensionally symmetric.
The use of these valves is in the common applications in heating and cooling technology, over-demanding applications in the field of conventional and nuclear energy to the use of aggressive media in chemical, pharmaceutical and food industries.
