“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

ERHARD nozzle check valves are designed for universal use and are particularly economical check valves for untreated and potable water as well as purified waste water due to their design.
Special features include the ultra-low pressure loss due to optimised flow cross-sections, a flow-efficient valve disc and valve stem gasket, as well as optimum hydraulic behaviour with short closing travel to minimise pressure surges.
Wakmet piston check valves made of forged steel prevent the backflow of medium into the pipe. The check valve can also be used as a shut-off valve to open and stop the flow.
Depending on the model, the temperature ranges extend up to 530°C or 670°C (up to ≤ 200°C for PTFE).
Wakmet metal seated piston check valves are mainly used in the energy sector as well as in the pulp and paper industry. Depending on the type, they are suitable for media such as water, steam, non-aggressive and non-toxic media as well as some also for gas, fuel and sea water.
