Overview

FLAME ARRESTERS
Flame arrestors are used to arrest the flame from reaching the highly dense area of fuel, incase of backfire and thus avoid accident and
explosions. When a flammable gas escapes through the safety relief valve to atmosphere it must pass through the flame arrestor which will
prevent the occurence of accidents/backfire. The flame arrestor should be installed prior to the burner to avoid flame propagation into the
upstream line due to backfire. These 3 models are without Non Return Valve.

SERVICE REGULATORS
These regulators are used in pressure reducing system for Natural gas or LPG. They are used to reduce the natural gas pressure from
2 4 kg/cm to 75mbar before supplying it to the domestic feeder line. These regulators are having built in over pressure shut off and under
pressure shut off valve and creep relief valve (safety relief valve).
