Pressure compensation valves - Import export

Pressure Compensated Throttle Check Valves PNDRV ▪ Throttle and shut-off the flow of liquid media in direction A-B (free flow in reverse direction) ▪ With pressure compensating feature via built-in compensating piston ▪ Designed for in-line assembly with female BSP, NPT and SAE threaded connections ▪ Graduated turning knob to accurately control flow ▪ Set-screw located on side of turning knob to lock valve in position ▪ Panel mounting nuts available on request ▪ Maximum working pressure: 210 bar / 3000 PSI

Monitoring of oxygen concentrations in bioprocesses in real time offers the possibility to learn about the actual metabolic state of the culture and use the information for process optimization. Values like OUR, OTR, RQ or even feeding strategies are essential for process control and optmization. BCP-O2 oxygen analyzers in the simple PA housing have a space saving design and are suitable for small scale stuides (e.g experiments in shake flasks) up to industrial scale processes. Due to the integrated automated temperature and pressure compensation gas cooling, specific valves or pipes are unnecessary. Gas concentrations can be measured directly in the process without expentiture.
