The micro solenoid valves are suitable for non-aggressive liquid and gaseous media that are compatible with the construction materials used in the valve. They are not suitable either for stagnating media or for media subject to vaporisation which deposit solid, calcareous, incrustant residues or similar. Maximum admissible viscosity: 3°E (22 cStokes o mm2/s). Minimum ambient temperature: -10°C; maximum ambient temperature: 60°C (class"A" or "F"). The minimum and maximum temperatures of the medium are shown in the table, according to the type of valve concerned.
N.B.: at very low ambient temperature, the medium can solidify and damage the solenoid valve.

MATERIALS
Body in brass, generally with female M5 threaded ports. Guide assembly in brass. Internal parts in stainless steel. Seals according to application: NBR (nitrile-butylene elastomer), FPM (fluorocarbon elastomer), EPDM (ethylene-propylene elastomer), PFPM (Perfluorate elastomer).

COILS
Comply with EC standards, directive 73/23CEE and relative modification 93/68EEC. Coils wound with class "H" wire, vacuum impregnated with polyester resin. Class "F" insulation (155°C) encapsulated in glass fibre reinforced PBT (polybutylene-terephtalate), or class "A" (105 °C) for latching versions, encapsulated in PP-VO (self-extinguishing polypropylene). Electrical connections at 2 poles plus earth (DIN 46340) or for micro plug connectors. Protection class IP65 EN 60529 with coil duly fitted with the plug connector. All the coils have obtained SEV-ASE (Swiss) approval and are suitable for continuous duty (ED 100%).

VOLTAGES
Standard: 24V/50Hz AC and 12-24V DC. Other voltages and frequencies supplied on request subject to minimum quantities: the windings in AC are designed for max voltage 24V only. Voltage tolerances: +10% -15% for AC; +10% -5% for DC. Standard voltage for latching versions: 6-12V DC; tolerance: + 10% -10%.

FLOW RATE
The flow factor Kv of each valve is indicated, so that the flow Q can be calculated as a function of the pressure drop Dp (see chart or formula). The Kv represents the flow of water, expressed in m3/h, at a temperature between 5°C and 30°C, that passes through the solenoid valve with a pressure drop of 1 bar (Standard VDI/VDE 2173).

RESPONSE TIME
The response time of sealing element depends on several factors but is usually lower than 10 milliseconds. Shorter response times are achievable by particular techniques.

USEFUL LIFE
The useful life of the solenoid valve is influenced by the pressure, temperature, type of medium and the voltage. Generally speaking, these solenoid valves are reliable for more than 20 million cycles and, in clearly defined cases and with special treatments, for a much larger number of operations.

OPTIONS 
On request, solenoid valves can be supplied for special applications to different designs and with different materials or performances. On request and subject to minimum quantities, the following can be supplied: different seals, body and guide assembly in chemically nickel-plated (Ni-P) brass, body and guide assembly in stainless steel, body in technopolymer, coil with flying leads.These special models are shown in the "Notes" of the tables. Also available with international approvals.


HOW TO ORDER
Always use the complete code, followed by the port size and the orifice diameter in mm. Specify the voltage and relative frequency for AC (e.g.V165B01-Z030A M5x1,1 V24/50Hz).
