Ambient conditions Icing, condensation and dew in and on the unit are not permitted. Avoid direct sunlight or radiation from red-hot surfaces on the unit. Note the maximum medium and ambient temperatures! Avoid corrosive influences, e.g. salty ambient air or SO2. The unit may only be stored/installed in enclosed rooms/buildings. The unit is suitable for a maximum installation height of 2000 m AMSL. Ambient temperature: -20 to +60°C (-4 to +140°F), no condensation permitted. Long-term use in the upper ambient temperature range accelerates the ageing of the elastomer materials and reduces the service life (please contact manufacturer). Storage temperature: -20 to +40°C (-4 to +104°F). Enclosure: IP 65. This unit is not suitable for cleaning with a high-pressure cleaner and/or cleaning products. Mechanical data Gas types: natural gas, LPG (gaseous), biogas (max. 0.1 %-by-vol. H2S) or clean air; other types of gas on request. The gas must be clean and dry in all temperature conditions and must not contain condensate. Medium temperature = ambient temperature. CE and FM approved, UL listed, max. inlet pressure pu: 500 mbar (7.25 psig). FM approved, non operational pressure: 700 mbar (10 psig). ANSI/CSA approved: 350 mbar (5 psig). Flow adjustment limits the maximum flow rate to between approx. 20 and 100%. Adjustment of the start gas rate: 0 to approx. 70%. Opening times: VAS../N quick opening: ≤ 1 s; VAS../L slow opening: up to 10 s. Closing time: VAS../N, VAS../L quick closing: < 1 s. Switching frequency: VAS../N: max. 30 x per minute. VAS../L: there must be a period of 20 seconds between switching off and on again so that the damping is fully effective. Safety valve: Class A, Group 2 pursuant to EN 13611 and EN 161, Factory Mutual (FM) Research Class: 7400 and 7411, ANSI Z21.21 and CSA 6.5. Valve housing: aluminium, valve seal: NBR. Connection flanges: Up to size 3: Rp to ISO 7-1, NPT to ANSI/ASME; size 2 and higher: with PN 16 ISO flange (pursuant to ISO 7005), with ANSI flange pursuant to ANSI 150. Cable gland: M20 x 1.5. Electrical connection: cable with max. 2.5 mm2 (AWG 12) or plug with socket to EN 175301-803. Duty cycle: 100%. Power factor of the solenoid coil: cos φ = 0.9. Electrical data for VAS 6–9/VCS 6–9 Mains voltage for VAS 6–8/VCS 6–8: 120 V AC, +10/-15%, 50/60 Hz, 230 V AC, +10/-15%, 50/60 Hz, 24 V DC, ±20%. Mains voltage for VAS 9/VCS 9: 120–230 V AC, +10/-15%, 50/60 Hz. Switching frequency: max. 1 x per minute. Max. temperature of solenoid coil: +20°C (+68°F) above ambient temperature. Current consumption at 20°C (68°F): Pick-up current: 1.8 A, holding current: 0.3 A.
