Semi-Automatic Switching Pressure Reducing Valve/Device 'Semi-Automatic Switching Semi-O TN-50 Series'
You can supply gas continuously! A device that switches over when one cylinder is empty.
The "Semi-Automatic Switching Semi-O" device divides the gas supply (cylinder) into two series, supplying gas from one series. When one cylinder is empty, it automatically switches to the other series. By simply replacing the empty cylinder with a filled one and operating the switching handle, continuous gas supply can be maintained. The switching can be done with a single pressure regulator, making it lightweight and compact. It is easy to carry and install, requiring minimal installation space. 【Features】 - Allows for cylinder replacement while supplying gas. - Simple operation with just a tilt of the switching handle. - Incorporates a small check valve at the inlet. - No gas will escape from the inlet during cylinder replacement (except for CVN type). - Can be used with flammable gases like hydrogen since it does not require electricity for series switching. - Option for a pressure gauge with contacts is available.
