Application :–

                            Used in Transformer or other sealed tank while Storing / Transportation to provide constant N2 / Inert Gas pressure so as not to allow atmospheric air & moisture.

Working :–

                     Gas regulator is used to automatically maintains a positive pressure of 0.15 to 0.175 kg / cm.sq. or as desired inside the connected  tank by help of  Twin attached High Pressure gas cylinder.

                   In case pressure falls below 0.15 kg / cm.sq.(or as set) due to leakage or temperature variation. Regulator automatically allows required additional gas to flow from the attached High-Pressure gas cylinder (not standard part of our item). This builds up the pressure. Double Stage regulation minimizes the risk. To know the inlet & outlet pressure, gauges are attached of 2.5” (63 mm) dial size, generally  confirming to IS 3624 for better readability.

                  Non Return Valve ( N.R.V.)  ensures that no gas passes from cylinder one to another even when one of  the gas cylinders gets empty. Safety valve at High-Pressure  & Low-Pressure  are attached so that if any unwanted pressure builds up in regulator is released.

                  L.P. hose normally 3600 mm. long is of rubber  (1 No.) with ¼” B.S.P. female thread outlet connection of Brass for Tank End. H.P. hose (2 No.) is normally 800mm. long each of annealed copper pipe (3/16”*5/16”)  fitted with brass socket of 5/8” B.S.P. male thread at cylinder end and 3/8” B.S.P. female thread at regulator end.

                 Complete assembly is packed in steel box  with locking arrangement to avoid pilferage during shipment / transportation. Painted with two coats of anti corrosive paint both inside & outside. Followed by glossy white color inside to give a better readability back ground for gauge & outside of light grey shade confirming to 631 of IS:5 or any other as desired.

Model available for single cylinder connection also.

Model available with Flexible Cylider Pressure Hose of Teflon with S.S. Braid.

Testing :–

1. ) Each assembly is tested for Functional & Leakage Test for 24 hrs by compressed gas after blocking outlet connection.
2. ) H.P hose is tested at 130 ±10 kg / cm.sq. for 15 minutes.
3. ) L.P hose is tested at 0.7 kg / cm.sq. for 15 minutes.

Mounting:- 4 Nos.slot are provided at 203*300 mm. P.C.D. for M-12 bolts for mounting or as desired.

Identification :- Each Regulator bears S.No., Month, Year of manufacturing for identification.

Special Features are:-

1. After connecting Twin Cylinders by help of  inlet copper hose. Pressure Guage shows the    actual cylinder pressure existing.
2. First Stage  regulated pressure is shown by L.P. Guage .
3. . Feature of automatic regulating the pressure desired after single setting thus no intermediate

      setting is required. Final Second Stage regulated outlet pressure is shown by Guage .

1. Normally the Stop Cock is Open existing Tank Pressures can be read in Guage by closing Stop Cock for 8-10 minutes.

Test Certificate :- Test Certificate is provided with each regulator for the above test performed
