 Applications 
 The 1780 series regulator is the regulator of a pipeline for the gas distribution system. For a variety of medical or industrial gases. The 1780 series regulator with balanced seat, and use of materials compatible with oxygen, but also with the BR-1780 series of the same brass body and internal parts. The performance of the BR-1780 series regulator. 
 Media: a variety of medical or industrial gas 
 Feature 
 ● The low temperature storage tanks can provide a variety of inlet pressure, the regulator can maintain the stability of the downstream pressure; 
 ● a large area of ??the valve seat and diaphragm to provide a high flow rate to ensure low pressure drop and the output pressure sensitive control; 
 ● 2 1/4 "FNPT gauge ports are located on both sides of the valve body; 
 ● 2 bonnet drain / vent holes to allow different mounting direction; 
 ? T-handle adjusting screw; 
 ● The maximum inlet pressure 2.8MPa (400PSIG); 
 ● three kinds of output pressure range; 
 Temperature range: -40 ~ 73.8 ° C (-40 ~ 165 ℉); 
 ● All 1780 Series are washed to achieve the Compressed Gas Association G-4.1, can be used for oxygen equipment. 
 Material 
 ● Body .............................. forging brass 
 ● valve cover .............................. nickel-plated aluminum 
 ● diaphragm ............... Nitrile with PTFE liner 
 ● springs and fasteners ..................... stainless steel 
 ● valve Other parts ....................... brass 
 ● The seat disc and O-ring ......... Viton (standard configuration) 
 Note: If the medium is carbon dioxide or nitric oxide, the valve seat and O-ring EPDM material shall be used, would also be required later in the model with "E" to distinguish. 
 Size: 
 Import and export of the 1780 series regulator connected size and has been popular 1680-series aluminum regulator. In other words, the 1680 series of the same type can use the new 1780 series instead of in order to obtain balanced seat, bring a better performance.
