What materials form the wetted surfaces for hygiene-sensitive uses?
Components include polybutylene terephthalate variants and polypropylene, paired with high-alloy stainless steel to reduce contamination risk in food-contact pathways.
Which sealing material is employed to maintain pressure integrity?
Sealing is achieved using nitrile rubber (NBR), chosen for resilience against oils and common industrial fluids.
How does the construction cope with corrosive or aggressive media?
The use of nickel-plated brass and stainless steel coupled with chemically resistant polymers provides layered protection against many corrosive substances.
What standards or approvals relate to particulate and purity considerations?
It conforms with ISO 8573-1:2010 particulate classifications and meets additional industry standards for safety and material restrictions.
Which temperature extremes can be expected during continuous operation?
The component is rated to perform reliably down to -10°C and up to 80°C under normal operating conditions.
