“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

The ChemValve Schmid dual plate check valve has an eccentric disc and a wafer design.
The flow-friendly design reduces the pressure loss in the system and therefore the energy requirements of the plant.
Another advantage of this valve is that no gland is required due to the design and so it is impossible for the medium to escape.
The dual plate check valve is used in all industrial processes involving liquids, gases or steam.
“RT gate valves valvole in cast design are used to prevent backflow in pipe systems. Due to their fully open design, this results in minimal pressure drop.
Design:
* The housing material is made of cast steel. The valves have a bolted or pressure seal bonnet (for higher pressure).
* The valve disc is made with forged material. On request, the disc can be supplied with an overlay of Stellite or other materials.
* The disc hinge joint is designed in such a way to achieve a
perfect tightness, which means a self-positioning disc system. “
