These data are based on material P235-265GH (sieve: 1.4301). Additional material 1.4541 / 1.4571 are available upon request. Technical
and design changes are permitted.
1)
Dimensions are acc. to DIN EN 558-1 and flanges acc. to EN 1092-1. Tolerances in acc. with norms DIN 8570 and DIN 28005.
Vertical measures (H, h, Amin) are based on PN 16. Customised dimension and designs are possible.
2)
Weight of the strainers can only be determined after the order is placed, due to the dimensioning of the strainer body
in connection with the planned operating pressures. Generally, the weights can differ from the mentioned ones.
3)
The mentioned zeta-value (ζ) needs to be increased by 20%, if the strainer comes with a double-layered sieve.
Generally, this is the case with strainers ≥ DN 250 and a mesh-size (MW) of 0.5 mm.
