Dome Bias Semi-Automatic Manifold
GM1 series dome-bias semi- automatic manifold system is designed to provide an uninterrupted gas supply. It consists of a primary bank and a reserve bank of cylinders. When the pressure in the primary cylinder bank reduces the preset value, the changeover takes place automatically to provide continuous supply of gas from the reserve bank. The priority handle should be manually switched during cylinder change.
Features
Semi-automatic Changeover System
• Fully enclosed, dust-proof metal cabinet
• Pressure gauge indicates gas source and outlet pressure
• Secondary regulator for consisent pressure and flow delivery to the pipeline
• Relief valve at outlet for protecting downstreampiping
• Pressure switch port is available
• Mechanical dome-dias changeover design
• Prior indicator valve
• Suitable for high flow systems; rated for 120m3/h (4200SCFH)* to 170m3/h (6000 SCFH)**
* When delivery pressure is 50 psi
** When delivery pressure is 180 psi
Pipeline
• Silver brazing on piping joints for maximum leak prevention
• System is designed to accommodate future expanison needs
• Optional external filter provides easy replacement of filter element
