Needles - Import export

Nova Swiss needle valves offer a high degree of safety and reliability, even under challenging operating conditions. The valves can be installed in both directions and provide an effective seal for both gaseous and liquid media. The heart of the valve consists of a specially shaped valve seat and a two-piece, non-rotating stem. Erosion of the stem is thereby avoided. The pressure-resistant parts are made of high-quality, corrosion-resistant stainless steel. Every single valve body is certified by us. For applications that are subject to particularly strict quality standards, we offer complete traceability of all our pressure-bearing parts. Nova Swiss high-pressure valves are supplied complete with screw fittings.

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.

Depending on the stirring or mixing task, Buchi reactors can be equipped with stirrers of different types. For gas entrainment as in hydrogenations, the Rushton type turbine stirrer is often used.
