EXTENSIONS FOR LOW FLOW
DruvaTEC® extension header kits for manifold
This extension header kits are used to increase number of high pressure inlet ports for manifolds in industrial gas supply systems for pure, inert, flammable, oxidising gases and gas mixtures.
TECHNICAL SPECIFICATION
Extension Header Kits were used to connect more than one gas cylinder on each side of the manifold. It can consist of diaphragm shut-off valve, tubing, inlet and outlet connection. Upon request, it can be equipped with check valves, gauges and vent valves, pressure transmitter and contact gauges. They can be delivered with up to 4 inlets. The Extension Header Kits are designed for safe handling of high purity gases.
SPECIAL FEATURES
- Up to four additional inlet ports are possible
- Variable, configurable system
- Extension Headers are optional equipped with manual actuated diaphragm valve, non return valve, gauge, contact gauge, pressure transmitter
- Complete kits are available
- Valves - developed, tested and produced in accordance with relevant sections of ISO 10297:2015 (including O2 ignition test for the main valve)
- Non Return valves -The special seat seal and the use of selected gas-wetted parts allow the use with Oxygen up to 300 bar
- Electrostatic chargeability test
Fulfills requirements according to ISO 80079-36, IEC TS 60079-32-1 and German TRGS 727
Usable in EX- areas zones 1 and 2 for gases with explosion risk group I, IIA, IIB, IIC
