    Pressure Regulator for Gaseous Media, type RG10 / RG40 DATA SHEET
RG 10/40
   

FEATURES :

  • Gas regulator /governor for gaseous media, to be fitted to all types of gas consuming appliances.
  • Design incorporates inlet pressure compensation  diaphragm ensuring high resolution.
  • Optimum dimension allows high volume throughout.
  • A purge line not required for DN15 to Dn150 size.
  • Fitted with separate working diaphragm and safety diaphragm, to ensure high degree of protection.
  • Outlet pressure range can be changed by fixing various colored coded standard springs.
  • Change in inlet pressure or change in volume, outlet pressure is ineffective.
  • Pressure damping valve provided as a standard accessory.
  • Separate models for 1 bar and 4 bar inlet pressure range.
  • Special version for bio gas.
CONSTRUCTION :

Design incorporates inlet pressure compensation diaphragms, ensures precise regulation.Large orifice dimension allows handling of high throughput.

Regulator incorporates working diaphragm, safety diaphragm and bleed diaphragm, as per DIN DVGW requirments.

Eachof the components undergoing gas pressure is treated with impregnation process to ensure safety to plant.
 
TECHNICAL SPECIFICATIONS :
Valve body and housing in Aluminum silicon alloy (AISi), free of defect, vacuum porosity sealed. Diaphragms manufactured from special non-vicking, nylon inserted Nitrile sheets imported from Germany, ensure no seepage of gas through diaphragm. Working parts of Aluminum. Valve disc specially formulated synthetic rubber material vulcanized to aluminium disc.

Flange connections are as per PN 16, DN 2501 or As per ANSI B 16.5 Class 150.
 
FLUIDS :
Natural gas, LPG, Ammonia, air, bio gas (on request), and all non-corrosive gases compatible to Aluminum body material.
 
PRESSURE RANGE :
RG 10 (for 1 bar inlet pressure), valve size available from 15 to 150mm
RG 40 (for 4 bar inlet pressure), valve sizes from 15 to 100 mm.

OUTLET PRESSURE :
DN 15 to DN 100 : 5 to 350 mbar.
DN 150 : 5 to 160 mbar

"ALL REGULATORS ARE SET TO 20 mbar OUTLET PRESSURE IN OUR FACTORY (RED SPRING) OTHER RANGES TO BE OBTAINED BY CHANGING GIVEN SPRING."

External impulse line size -RP 1/4" for size 15 and 25 mm, 3/8" for DN 40 to 150 mm.
All valves are provided with RP 1/4" connections at inlet and outlet side; are plugged, to be used as pressure test points or for connection pilot gas line.

(-) 15°C to 60 °C Regulators confirm to current standard of EN334, Regulation Group RGXXR/A/F10 & RGXXR/A/F40 (1 & 4 bar)and closing pressure group SG30. Strainers which are possibly provided
in the regulators, serve as flow straighteners. Regulator fitting position in the pipeline is irrelevant. However, this device must be fitted in the pipeline which is free of tension and must not touch any surrounding constuctions (wall, brick, work, etc.) It is necessary to maintain minimum 20mm distance from the surrounding walls.

In accordance with EN 746-2 for gas pressure regulating plants, where inlet pressure is in excess of 100 mbar; is required to be fitted with Safety Shut off Valve (SHV), prior to gas regulator/ governor, Safety Relief Valve (SRV), after gas regulator.

Flanged Bolts, Nuts and Washers Can
Be Supplied

WHEN CHANGING THE SPRING, THE SPRING ADJUSTING SCREW HAS TO BE EXCHANGED FOR A STRONGER VERSION.

Fitting of Damping valve for model RG 15 and RG 25 not required. For RG 1 bar ande RG 4 bar pressure, damping valves are supplied loosely
tied down with the valve. They are required to be fitted, if found necessary.

While installing impulse line, please observe a diagram. Nipples are provided with the valves. Use Aluminum pipeline connection to RP¼ for DN
15 and DN 25, connection RP 3/8 for DN 40 to DN 150, connected to the outlet side at a distance not lesser than 5 x diameter of valve.

Outlet velocities: AVCON recommends avoiding velocity of low flow above 30 m/sec in the outlet pipe. In order to maintain a steady regulation and has smooth operation with higher velocities; the next bigger size of outlet pipe should be chosen.
