Description
Description:
This series of solenoid valves is of normally closed type, suitable for civil and industrial applications, supplied with alternate or direct current. These valves are divided into two groups: with 8 mm or 10 mm orifice. The valves marked with “S” or “L” after their type reference have a coil operating in direct current, which has enabled to make their actions as noiseless as possible. It is possible to have valves provided with upstream or downstream pressure test point (excluding the ones with G1/4” connection) and, for 10 mm orifice versions only, valves equipped with hydraulic brake unit, enabling slow opening; in this case it is also possible to have an adjustable quick opening initial flow. The valves of this series, conforming to EN161, have a CE type Certificate (CE Reg. N° 63AQ0626) in accordance to the European Directives 90/396 and 93/68. − EC- type certification in accordance with the new European Gas Appliances Regulation (EU) 2016/426 (GAR); − conformity to EC Low-voltage directive 2014/35/EU − AGA- type certification (Certificate no. 4314 rev. 10) in accordance to standard requirements AS 4629-2005 (Incorporating Amdt 2).
Directions For Installation And Maintenance
This valve is a safety appliance and should not be modified. The manufacturer’s responsibility and guarantee are invalidated in case the device is tampered with by the user.
• The applicable national regulation and European standards (Ex. EN 60335-1 and EN 60335-2-102) related to the electrical safety must be respected;
• 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 wrench 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.
• All operations (installation, maintenance, etc.) must be carried out by a qualified technician.
• Before any connection operation, completely isolate the system from power supply (multi-pole disconnection). Place the system safely to avoid accidental switch-on and make sure there is no voltage. If the system is not switched off, there is a risk of electric shock.
• During and after any operation (installation, maintenance, etc.), make sure that the type and code are the ones provided, check the correct functioning and the internal and external thickness of the valve.
• In the event of a fall or impact, the valves must not be started, as safety functions may be compromised even if no damage is visible to the outside.
