The Gazkon model GSR200 HP/LP is a direct action, spring controlled, pressure reduction regulator. Normally used for the supply of gas to residential complexes, commercial applications, small industries (burner, boiler and process applications) and smaller antenna networks. As standard the GSR200 regulators can be used on natural gas, LPG and most clean dry gasses. Two versions are currently available: • GSR200 LP for outlet pressures from 21 to 50 mbar, • GSR200 HP for outlet pressures of 50 to 300 mbar. Both versions utilize a fully balanced valve plug. This ensures that the outlet pressure is maintained at the required setting even with changes in the inlet pressure. As an option the GSR200 regulators can be equipped with a safety shut off valve which closes off the gas supply immediately and totally in the event of a problem. Operation is by the outlet pressure reaching an adjustable pre-set over (high) or under (low) pressure setting. Manual re-set. As an optional feature the GSR200 can be fitted with a limited capacity internal relief valve.
