Outlet valves - Import export

Bottom outlet valves Inner diameter: DN3 - DN25 Temperature: 350 °C Pressure: 350 / 500 bar - 5000 / 7000 psi Material: stainless steel, Hastelloy®, Titanium etc. Buchi bottom valves are very compact, available for different operating conditions and functions. Solenoid bottom valves with a pneumatic actuator are used for automated opening / closing with signal feedback of the status.

Nutsche filters for reactors and pilot plants Glass vessel: 10, 30, 50, 100, 140, 300 liter Pressure: -1.0 (FV) to +0.5/ 1.0 bar Temperature: -60 °C to +200 °C Filter cloth: Mesh size 8 to 115 micron Material: Borosilicate glass 3.3, PTFE, PFA, ETFE A clean-room setup and other materials are available to meet your specific process requirements. Buchi nutsche filters can easily be combined with our reactors for solid / liquid separation after the synthesis. The inert materials allow safe processing in an inert atmosphere of a wide range of solvents and acids in a completely sealed (buchiflex) glass system under full vacuum. The slurry is transferred into the filter. The solid content in the slurry is held back by the filter cloth forming a filter cake, while the filtrate runs away to the outlet valve in the bottom plate. The filtering stage ends when the filtrate is of small quantity, which can be shortened by squeezing the filter cake by turning the height adjustable stirrer.
