Size extension for this erosion-resistant control valve

The portfolio of Neles ceramic E-Series control valves (photo), recognized for being extremely erosion resistant, has now been expanded to NPS 8 in. (DN 200) in pressure Class 300 (PN40). The E-series valve is the most erosion-resistant control valve available.…

Translucent tubing for peristaltic pumps in high-purity operations

APSPG tubing is specially formulated to withstand the repeated compression and release actions of peristaltic pumps and offers consistent performance in pharmaceutical, biopharmaceutical and laboratory uses. Made of platinum-cured, low-volatile-grade silicone material, the finished tubing carries the United States Pharmacopoeia…

New explosion-proof actuator for chemical applications

This company now offers its new SQEx.2 part-turn actuator  — the explosion-proof version of its SQ actuator, which was introduced at the beginning of 2013. In line with qualification requirements for hazardous environments, the SQEx.2 meets the European ATEX and…

Precise dosing with multi-port, fluoroplastic valve blocks

This multi-port valve block from the iComLine Series is made of ultra-pure PVDF and features innovative seat-diaphragm technology with PTFE. This combination allows very heavy-duty switching cycles and temperature resistance up to 150°C — features that are not possible with…
