Solutions
Choose by duty
Check and control valves
Swing and ball check valves against backflow, and the Imperium9 control valve for regulation.
Strainers
PFA-lined T-strainers with PTFE baskets that protect pumps, control valves and instruments.
Sample valves and sight glasses
Take samples without opening the line, and see flow, colour and level — also as Clean Room Series.
Spare parts
Spare parts for GFT9 products — and for equipment of other makes: send us the part, we measure, document and manufacture it.
Custom-made
PFA-lined and all-PFA parts to your drawing: machined, lined and tested in one house, from one fitting to large equipment.
