Elektrogas Solenoid Valve for Gas VMR Series

Features:

• The valves are made of aluminum alloy die-cast (or hot-pressed brass for OTN versions), with a wide range for inlet/outlet connections from DN 8 (1/4”) up to DN 150 (6”).
• 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.
• he 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 flow rate adjustment (except brass models).
• An incorporated fine mesh filter protects the valve seat and disc as well as downstream components and prevents dirty contamination (except brass models and 6 bar).
• 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 (except brass models), to connect manometers, pressure switches, leakage detectors 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. 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.
