Danfoss Gas valve E8/B DFD 1/4M 220V 1 bar

E8/... SERIES SOLENOID GAS VALVES WITH 1/8” and 1/4” CONNECTIONS AND OPERATING PRESSURE UP TO 1bar. GENERAL DESCRIPTION This series of solenoid valves are of normally closed type, suitable for civil and industrial applications, supplied with alternate or direct current. E8/S version, which can be fitted with a flow adjustment device and outlet pressure plug, are supplied with alternate current, but provided with an inside rectification circuit, which permitted to make actions as silent as possible. Gas valves of this series, conforming to EN161, have a CE type Certificate (CE Reg. N° 63AQ0626) in accordance to European directives 90/396 and 93/68. TECHNICAL FEATURES Class: A Group: 2 Supply voltage (1): 230Vac / 50-60Hz 110Vac / 50-60Hz Operating temperature: -10°C / +60°C Closing time: ≤ 1s Opening time: ≤ 1s Mounting: vertical and horizontal Body: die-cast brass (1) Versions with different supply voltages are available. INSTALLATION • Respect the applicable national and European standards (e.g. EN60335-1) regarding electrical safety. • Assemble the valve to the installation so that the arrow on the valve body has the same direction as the fuel flow. • During the assembly of the valve to the installation piping, avoid twisting on the sheath and always use an hexagonal key to be fitted to the valve body. • Make sure that no foreign matters have entered the valve body. • Make sure that the max. fuel input pressure never exceeds the value appearing on the label. 4080_r01 1/4 FLOW ADJUSTMENT FOR E8/SR... After removing the top protection, rotate clockwise the screw marked with 1 in Fig.1 to reduce the flow, rotate it counterclockwise to increase the same. 1 Fig.1 E8/B FIXING Nut: G1/4" Ogive Es. ch. 16 φ6 φ 6 orifice OVERALL DIMENSIONS 2/4 4080_r01  DIAGRAM PRESSURE mbar FLOW RATE 3 m/h A: standard flow rate m 3/h of NATURAL GAS dr 0.554 B: standard flow rate m 3/h of LPG dr 1.54 C: standard flow rate m3/h of TOWN GAS dr 0.411 D: standard flow rate m3/h of AIR dr 1 SUMMARY TABLE Type Operating Orifice Connections Weight Coil Consumption Consumpti Flow Possibility pressure diameter (g) (VA) on (m³/h to fit (mbar) (mm) (VA) gas with pressure 230Vac ∆P test point 110Vac 2.5mbar) E8/B 0 ÷ 1000 4 1/4" M 243 BE7*D3C 10 10 0.5 No E8/B 0 ÷ 1000 4 1/4" M 222 BE7*DFP 10 10 0.5 No E8/B 0 ÷ 1000 4 1/4" M 222 BE7*DFD+MPM182 10 10 0.5 No E8/B 0 ÷ 1000 4 1/4" M 243 BE7*C3C 7 7 0.5 No E8/B 0 ÷ 1000 4 1/4" M 222 BE7*CFP 7 7 0.5 No E8/B 0 ÷ 1000 4 1/4" M 222 BE7*CFD+MPM182 7 7 0.5 No E8/L 0 ÷ 1000 4 1/8" F 230 BE7*D3C 10 10 0.5 No E8/L 0 ÷ 1000 4 1/8" F 220 BE7*DFP 10 10 0.5 No E8/L 0 ÷ 1000 4 1/8" F 220 BE7*DFD+MPM182 10 10 0.5 No E8/L 0 ÷ 1000 4 1/8" F 230 BE7*C3C 7 7 0.5 No E8/L 0 ÷ 1000 4 1/8" F 220 BE7*CFP 7 7 0.5 No E8/L 0 ÷ 1000 4 1/8" F 220 BE7*CFD+MPM182 7 7 0.5 No E8/S 0 ÷ 100 6 1/4" F 280 BE7*GMO 7 7 0.8 Yes E8/S 0 ÷ 100 6 1/4" F 260 BE7*C3C 7 7 0.8 Yes E8/S 0 ÷ 100 6 1/4" F 250 BE7*CFP 7 7 0.8 Yes E8/S 0 ÷ 100 6 1/4" F 250 BE7*CFD+MPM182 7 7 0.8 Yes E8/S 0 ÷ 100 6 1/4" F 250 BE7*CFD+MPM532 7 7 0.8 Yes E8/SR 0 ÷ 100 6 1/4" F 290 BE7*GMOE 13 7 0.8 Yes E8/SRP 0 ÷ 100 6 1/4” F 290 BE7*GMOE 13 7 0.8 Yes E8/SB4 0 ÷ 200 4 1/4" M 225 BE7*C3C 7 7 0.5 No E8/SB4 0 ÷ 200 4 1/4" M 235 BE7*CFD+MPM182 7 7 0.5 No 4080_r01 3/4  TYPE REFERENCES E8 / S R P * G MO 230/50-60 Supply voltage Type Description Type 110/50-60 110Vac/50-60Hz 230/50-60 230Vac/50-60Hz Body type Connection type Body Connections Orifice B G1/4” M 4 mm Type Description L G1/8” F 4 mm 2C Connection with two core cable- S G1/4” F 6 mm IP65.
