GAS PRESSURE REGULATORS-STABILIZERS
Pressure regulators-stabilizer is a device designed for reduction, regulation and maintenance of the pressure (flow) of hydro carbonated gases, gaseous phases of liquefied gases, compressed air as well as other non-aggressive gases constant at the outlet within prescribed limits regardless of inlet pressure. Pressure regulators-stabilizers can operate without external power source.
FIELD OF APPLICATION:
Gas distributing plants, heating plants, gas reciprocating engine power plants, gas burners and other equivalent equipment and installations, which require reduction and maintenance of the constant value of gas flow rate pressure.
MAXIMUM OPERATING PRESSURE:
- up to 6 bar
DIAMETER NOMINAL:
DN 15÷150
HOUSING MATERIAL:
- aluminum;
- steel.
VERSIONS:
1. Standard version (DN 15÷150) - designed for reduction, regulation and maintenance of the gas pressure within prescribed limits.
2. Regulator with in-built safety relief valve (DN 15÷150) – designed for reduction, regulation and maintenance of the gas pressure within prescribed limits and has function of gas discharge to the atmosphere (gas path) in case if controlled pressure is exceeded.
3. Combined regulator both with safety shut-off (DN25÷100) – designed for regulation and maintenance of the gas pressure within prescribed limits, and also stops gas supply, when prescribed gas outlet pressure is exceeded.
4. Combined regulator, both with safety shut-off valve and safety relief valve – designed for regulation and maintenance of the gas pressure within prescribed limits; has function of gas discharge to the atmosphere (gas path) when controlled pressure is exceeded, and also stops gas supply, when prescribed gas outlet pressure is exceeded;
Combined regulators-stabilizers can be manufactured in following versions:
- with safety shut-off valve and safety relief valve in separate housings.
- with safety shut-off valve and in-built safety relief valve.
- with safety shut-off valve and safety relief valve in one housing (monoblock unit version).
- combined household regulator, both with safety shut-off valve and safety relief valve. Such regulators are applied at the gas supply systems of residential and small-apartment houses as a part of household gas distributing plants.
5. Zero pressure regulator (DN 15÷150) - designed for proportional regulation of gas flow rate depending on rarefaction at the outlet or at the control point of pipeline, and maintenance of gas-air mixture in a constant ratio.
6. Gas-air pressure ratio regulator (DN 15÷150) - designed to obtain a gas-air mixture in the required ratio and automatically maintain this ratio.
CLIMATIC VERSIONS:

PRESSURE SWITCHES
Pressure switches are used as excess-pressure and under-pressure differential monitoring devices for natural gas, liquified gas and air in gas supplying and ventilation systems.
Pressure switches monitor extremely slight pressure differences and provide for electrical disconnection of a system when the set value is reached.
