GOK two-cylinder system with automatic changeover 37/50 mbar, 6 kg/h - Kombi high-pressure hoses 450 mm, for cylinders up to 33 kg
- Ready-to-fit GOK two-cylinder system with automatic changeover and a 37/50 mbar regulator rated at 6 kg/h. When one cylinder runs empty, gas keeps flowing from the other.
The GOK two-cylinder system is a complete set for supplying gas from two cylinders. The automatic changeover valve draws gas from the service cylinder and, when it runs empty, switches to the reserve cylinder by itself. The low-pressure regulator delivers 37/50 mbar at a flow rate of up to 6 kg/h. The set is designed for cylinders with a filling weight of up to 33 kg and works well in homes, workshops, catering and small businesses.

How the automatic changeover works
- gas is drawn from one cylinder, the other waits as a reserve
- when the service cylinder runs empty, the valve switches to the reserve by itself
- the indicator on the knob shows which side is in use and when to replace the empty cylinder
- you replace the empty cylinder without interrupting your appliances
- a built-in safety device limits gas escape while a cylinder is changed
- GOK also offers an optional electronic service/reserve indicator with display
Where it is used
- home heating and cooking supplied from cylinders
- catering, stalls and workshops
- sites where an interruption of the gas supply is a problem
- systems with cylinders placed outside the building, in a cylinder box or cabinet
Installation and safety
- installation and commissioning should be done by a qualified person or an installation company
- cylinders must stand upright while gas is drawn
- do not mount the regulator lower than the cylinder valves
- check the joints for leaks with a leak detection spray, never with a flame
- in a closed room, connect a vent line to the regulator relief outlet and route it outdoors
- the fittings have a DIN DVGW type test certificate or an EU type examination
