DIN piston check valve
“LDM piston check valves are self-acting valves to prevent unwanted backflows. They are designed for long-term and maintenance-free operation.
Depending on the version, the valves are closed by the weight or by an additional spring.
These models are also available in oil and grease-free versions.
Nominal diameters from DN15 – DN200
Nominal pressure PN16-PN40
Temperature range of -10°C to +400°C
DIN swing check valve, forged
Wakmet check valves prevent the backflow of medium into the pipe.
The forged welded design prevents material defects such as cracks or porosity and excludes non-metallic impurities.
A completely open disc provides a full bore so the flow rate remains unaffected. A version with a bypass valve is available on request.
The metal seated DIN check valves KZS/KZK are mainly used in the energy sector for energy applications as well as in the pulp and paper industry.
