Product information

Product range

NovaLab laboratory valves have been developed for the extraction of liquid and gaseous flow materials, as required in laboratories in industry, research and teaching.

In their design and manufacture, the valves comply with all regulations, guidelines and standards applicable in the laboratory sector.

Production is carried out according to the modular principle as a single tapping point or as a combination of valves to match the well-known laboratory equipment.

The operating handles of the NovaLab laboratory valves mark the connected flow material with their entire surface, coloured according to DIN EN 13792.

At NovaLab, a distinction is made between valves and taps. The four-blade operating handle stands for valves for the extraction of water and technical gases.

Disc valves for natural gas and liquefied petroleum gas are equipped with a double-blade operating handle. Valves and taps have different handle mounts to avoid confusion.

For safety reasons, the flow material of the valve must be taken into account when replacing operating handles on laboratory fittings. Tops and couplings for natural gas and liquefied petroleum gas are not supplied as spare parts for safety reasons.

Another focus of the NovaLab product range is a comprehensive range of emergency shower fittings. The installation of these first aid facilities is mandatory in laboratories and production plants where hazardous substances are handled. Elements of emergency shower facilities are body and eye washes, which are listed in a separate catalog.

NovaLab laboratory valves are subjected to a function and leak test at the factory. 
They are suitable for the following operating pressures:

for water,
including fully desalinated water 10 bar
for technical gases 6 bar
for compressed air 10 bar
for natural gas and liquefied petroleum gas 200 mbar

Materials

The valve housings are made of non-porous brass. Lead- and cadmium-free materials are used for all solder and adhesive joints.

The housings are coated on a blasted surface in an electrostatic powder spray (EPS) process with a layer thickness of approx. 60-150 μm. This special epoxy resin-based plastic coating ensures high resistance to chemicals such as acids, alkalis and solvents. It has excellent adhesion with optimal impact and impact resistance.

The standard colour of the laboratory valve housings is light grey (RAL 7035), while the laboratory valve housings can be obtained in silver grey (RAL 7001) at no extra cost. Special colours are available on request at an additional cost.

Laboratory valves

NovaLab laboratory valves comply with DIN 12918-1 and are supplied with upper part G1/2" with non-rising spindle. The volume is regulated by several turns of the four-leaf operating handle. Sealing is done with an elastic cone sealing disc. In addition, there are tops with ceramic sealing washers.

Valves for water have hose nozzles that can be removed in accordance with DIN 12898. For aggressive flow materials, such as fully desalinated water, all water-bearing parts are chemically nickel-plated. Plastic versions made of PVDF and stainless steel versions complete the product range. Installation note: Chemical nickel-plated copper connection pipes must not be bent or soldered!

NovaLab laboratory valves for technical gases and compressed air are equipped with a needle dosing regulation for the constant delivery of the smallest flow rates. Valves for vacuum are roughly controllable.

In the case of gas valves, the hose nozzles are firmly attached to the arm in accordance with DIN 12898

Laboratory disc taps

NovaLab laboratory disc valves are suitable for natural gas and liquefied petroleum gas. The valves comply with DIN 12918-2 and the rules for gas valves in utility plants. They are recognized and approved by the German Technical and Scientific Association for Gas and Water (DVGW).

NovaLab natural gas and liquefied gas fittings are operated with a 90° rotation of the double-leaf operating handle. The handle position also marks the operating status of the valve. If the handle is parallel to the hose nozzle, the valve is open, if it is in a transverse position, it is closed.

In addition to the version with a fixed hose nozzle, NovaLab disc valves are also available with a sealing coupling and plug-in nozzle, which enable a particularly user-friendly connection and disconnection of the hose line from the tap point. 

For optimal sealing, the disc valves are equipped with ceramic sealings. A safety lock prevents unintentional opening of the valve. The operation is only possible after pressing in the two-leaf operating handle.

Columns

NovaLab laboratory columns are offered in different heights. Columns for water, e.g. in the standard version 200 and 300 mm, have a column base diameter of 55 mm. Columns for gases with a height of 90 mm are equipped with a column base diameter of 50 mm. The column feet can be equipped with an anti-rotation device (tension pins).
