LDM spol. s r. o. was founded by three partners in the middle of 1991. Since its independent establishment it has been, still is and will be focused on the production of industrial valves, especially control valves in pressure stages PN 16 to PN 500 and in dimensions DN 15 to DN 400.
We are ready to offer you products from the entire LDM range including valve specifications according to your requirements. The long-standing cooperation with LDM has set very good business conditions for our company.

Control valves are valves used to regulate the flow and pressure of the flowing medium. In the three-way design, they are then used to mix or divide the flow of the medium.
Shut-off valves are used to close or shut off pipelines under all normal operating and non-operating conditions. When equipped with electric or pneumatic actuators, their use is mainly in automated plants. Emergency shut-off valves are control or shut-off valves equipped with an actuator with an emergency function to ensure safe shut-off of the valve in the event of a power failure.
In the LDM product range, these valves occupy the largest area of the product portfolio. They are available in pressure classes from PN 6 to PN 500, with a range of nominal clearances from DN 15 to DN 400. Valve designs can be two-way straight or corner valves, or with an extended outlet port. Three-way control valves are generally dimensionally symmetrical. The applications of these valves range from common applications in heating and cooling technology, to demanding applications in the conventional and nuclear power industry, to applications for aggressive media in the chemical industry, pharmaceutical industry and food industry.
Outlet pressure regulators
Pressure reducing valves or outlet pressure regulators are self-acting valves used to maintain a constant pressure of the medium at the outlet side of the valve. The whole process is ensured by maintaining the pressure balance on the diaphragm, in case the consumption of the medium stops, the valve is closed.
In the LDM product range, these products are available in PN 16 and PN 25 versions, the range of nominal clearances is limited to DN 50.The
use of pressure reducing valves is mainly in the heating industry and in industrial water and air distribution

|Direct-acting differential pressure controllers DN 15 to 50, PN 16, Kvs 2 to 20 m 3 / hour|
|BEE line RD 122 D and RD 122 P Direct-acting differential pressure regulators and direct-acting differential pressure regulators with flow restrictor DN 15 to 50, PN 25, Kvs 0.63 to 32 m 3 / hour|
Differential pressure regulators are self-acting valves used to maintain a constant pressure differential across the equipment. This is achieved by maintaining pressure balance in a control head fitted with a diaphragm and associated valve cone. LDM offers these valves in sizes DN 15 to 50 and in pressure classes PN 16 and PN 25. They can be equipped with a flow restrictor to ensure that the maximum flow through the system is limited. They are mainly used in cases of central heat supply on UT distribution lines, as balancing valves in locations with different layout pressures.
