German reducer valve for gas bottle small - high pressure 0-2 bar, threaded W21.8 x 1

Reducer valve for high pressure of the German brand SRG. Type: small. Made of brass. It is mounted on a gas cylinder and provides pressure reduction of the gas that is supplied from the cylinder to a gas appliance. The connection is made by means of a thread. It serves to supply propane-butane to industrial appliances with greater power and gas consumption. It is used in burners, heaters, large radiators, etc.
The reducer valve has a regulator that determines the amount of supplied gas. The transition from a lower to a higher grade should be gradual, not sudden.
Connecting thread: W21.8 x 1. The working pressure of gas appliances should be 0-2 bar.
Since most western appliances are equipped with gas reducers that do not meet our domestic cylinder standard, this reducer valve is used and the same is wound onto it. The reducer valve is suitable as a transition between European standard reducers with W21.8 LH thread and household bottle with Jumbo valve - G56.
