Governors for gas J78R

J78R

Spring-loaded governor with inlet pressure compensation diaphragm and zero shut-off, for maintaining a constant set outlet pressure pa when gas throughput fluctuates,

J 78R for gas, J 78R..L for air, EC type tested and certified.

DN: 15,

connection: thread,

pe: max. 100 mbar,

pa: 6 to 55 mbar.

Governors for gas VGBF

VGBF..F

VGBF..R

Spring-loaded governor with inlet pressure compensation diaphragm and zero shut-off, for maintaining a constant set outlet pressure pa

when gas throughput fluctuates, with safety diaphragm, so no purge line required, for gas, EC type tested and certified.

DN: 15 to 150,

connection: thread or flange,

pe: max. 0.5 bar, 1 bar or 4 bar,

pa: 5 to 350 mbar.

Air/gas ratio controls GIK

GIK..F

GIK..R

Air/gas ratio controls for maintaining a constant gas/air pressure ratio of 1:1, GIK for continuous control, GIK..B for high/low/off control, EC type tested and certified.

DN: 15 to 150,

connection: thread or flange,

pe: max. 200 mbar,

pG: 0.2 to 119 mbar,

Δp: max. 100 mbar.

Safety relief valve VSBV

VSBV

Safety relief valve to reduce short-term pressure surges or to prevent gradual increases in pressure caused by gas leaks, for gas, EC type tested and certified.

DN: 25,

connection: thread,

pe: max. 4 bar,

Safety overpressure slam shut valves JSAV

JSAV 25

JSAV 40R

JSAV 50-100F

Safety overpressure slam shut valve to secure all downstream fittings against too high gas pressure, with safety device, so no purge line required, for gas, EC type tested and certified.

DN: 25 to 100,

connection: thread or flange,

pe: max. 4 bar,

Speed and relief governors VAR

VAR..R

VAR..F-4

Relief governors for maintaining constant pressures in gas consumption equipment or for relieving brief pressure surges in control systems, in particular upstream of large-scale burners, speed governors for compensating for pressure fluctuations occurring on compressors or fans as the result of different flow rates. The governors comply with the requirements of EN 88, Class A, Group 2.

DN: 25 to 150,

connection: thread or flange,

pe: max. 200, 500 or 1000 mbar,

relief pressure range pa: 10-500 mbar.

Variable air/gas ratio controls GIKH

GIKH

Variable air/gas ratio controls for maintaining a constant gas/air pressure ratio of 4:1 on systems with air pre-heating, GIKH for continuous control, GIKH..B for high/low/off control, EC type tested and certified.

DN: 25,

connection: thread or flange,

pe: max. 200 mbar,

Δp: max. 100 mbar,

ΔpL: 0.15 to 30 mbar,

pG: 0.2 to 120 mbar.

Hot air pilot system WPS

For all gas-fired industrial furnaces with combustion air preheating where it seems good practice to maintain a stoichiometric combustion and to keep the gas consumption to a minimum.
