Safety solenoid valves for air and gas slow opening and fast closing Elektrogas VML valve model VML60 type valve is a safety valve that is normally closed, with fast or slow opening and an adjustable rapid section for initial gas flow. When not in the working position the spring works on the disc keeping the gas passage closed. When the coil is powered the valve opens rapidly in the first section of the flow, then slowly, with adjustable speed. When power is switched off the valve rapidly shuts.

Elektrogas VML valve model VML60 of a device is suitable for gas and air blocking and adjusting controls in atmospheric burners or fan-assisted burners, in industrial kilns and in all gas equipment which use gas solenoid valves (qualified for continuous service – 100% ED).

Features

  • The valves are made of aluminum alloy die-cast, with a wide range for inlet/outlet connections
    from DN10 (3/8”) up to DN80 (3”).
  • Sealings are made of NBR-based rubber certified for use with gas (EN 549).
  • Suitable for use with air and non-aggressive gases included in the 1, 2 and 3 families (EN 437).
  • Special versions suitable for aggressive gases, free of non-ferrous metals and with FPM seals.
  • Pipe connections meet Group 2 and backpressure sealing is compliant with Class A, according
    to EN161 requirements.
  • The whole range can be provided in Ex-proof execution, for use in Zones 2 and 22, according to 2014/34/EU Directive (ATEX).
  • The valve is open only when energized: if, for any reason, power supply goes down, the valve
    closes immediately (intrinsic safe).
  • Suitable for heavy-duty cycle operation and qualified for continuous service (100% ED).
    Equipped with max. flow rate and start flow rate adjustment.
  • An incorporated fine mesh filter protects the valve seat and disc as well as downstream components and prevents dirty contamination (except 6 bar models).
  • Provided with G1/8 connection to fit a proof of closure switch or a visual indicator.
    Provided with 1/4″ pressure gauge on two sides in the inlet chamber, to connect manometers,
    pressure switches, leakage tester or other gas equipments. Flanged models are provided with
    gauges also in the outlet chamber.
  • The coils are provided with terminal box or with ISO 4400 plug (optional). Both systems are
    provided with suitable cable gland to avoid water and dirty contamination.
  • All components are designed to withstand any mechanical, chemical and thermal condition
    occurring during typical service.
  • Effective impregnation and surface treatments have been used to improve mechanical sturdiness, sealing and resistance to corrosion of the components.
  • Valves are 100% tested by computerized testing machineries and are fully warranted.
