TECHNiCAL DATA pressure (bar): temperature (°c): Sample volume (ml): GENERAL APPLiCATiONS To take a sample from reactors or vessels containing: • poisoned media's • biological media's • corrosive media's • environmental unfriendly media's • liquids with high viscosities additionally the pV reactor sampling unit allows the operator to view the reaction process stage via an integrated sight glass. FEATURES • extracts a representative sample from a reactor under process conditions without stopping the process or opening the reactor. • Safe and simple operation. • Sample is transferred pressure less. • Different sample volumes are available. • ah wetted parts are pTFE, pFA, perfluor or glass. • Direct mounting of all auxiliary valves via integrated mini mounting flange. • if pH metering is required the top flange of the pV unit can be equipped with the required connection. • Unit can be connected to a continuous recirculation pump. • Unit can be integrated with vacuum, nitrogen and rinsing supply lines. • liquid product can be added to the reactor via the pV unit. • Sample media can be returned to the reactor. • No contamination of the atmosphere. Displaced air in the bottle is returned into sight glass. • Soft seated check valve prevents entering media in the vacuum line. • Unit can be flushed and rinsed in situ. • All valves can be pneumatically actuated. • numerous varieties of auxiliary valves and accessories. the unit can be integrated with various sensor devices to measure Redox, pH or temperature of the chemical process inside the reactor. www.valves.emerson.com © 2017 Emerson.

NEOTeCHA Reactor Sampling Type PV Description of operation Process Step A: All valves are closed: (3), (8), (13) and (15). Process Step B: By opening valves (3) and (8), the liquid from the reactor is lifted with vacuum through the suction hose (10) inside the dip tube through the open ball valve (8) into the sight glass (5). The PTFE hollow ball (6) floats on the rising liquid level till the ball will interrupt the vacuum on valve seat (2). This will prevent the liquid entering the vacuum line. Process Step C: As soon as the sight glass is full, the main shut off valve (8) can be closed, thereafter...

NEOTeCHA Reactor Sampling Type PV Modular conception The modular concept of the PV reactor can be tailored to virtually every customer sampling requirement. The volume of the sight glass is smaller or equal to the size of the sampling bottle to eliminate spilling by human error. 150, 250, 500 and 1000 ml samples volumes are available. We offer various solutions for heat tracing on auxiliary valves as well as to the main PV unit. The transfer device and auxiliary valves used for the vacuum or for rinsing media are available either manually or pneumatically operated. The unit can be utilized to...

NEOTeCHA Reactor Sampling Type PV Rinsing and cleaning Two ports only is what it takes to completely rinse and clean the reactor sampler without dismounting any component. Connection port A allows rinsing: sight glass, transfer device, main valve and suction hose (yellow area). Connection port B allows rinsing: the area between the suction hose and dip tube (green area). Continuous flow circulation If a continuous or almost continuous metering is necessary like for instance temperature, pH or Redox metering, it is possible to equip the PV unit with a diaphragm pump, which produces a continuous...
