Combustion
These are used for automation, for the security of combustion equipments for boilers, furnaces, etc, and for the oil and petrochemical industries.
1330/2030, 1332 and 1388 Series valves are especially designed to comply with the Resolutions, Regulations and Recommendations for the use of Natural Gas in industrial installations.
They may be used with other gases, such as LPG, propane, manufactured gas, etc, as well as with air or any other non combustible neutral gas.
The maximum working pressure for 1330/2030 series Normally Closed diaphragm valves, when used as relief valves in Natural Gas burners, is 0.160 kg/cm2.
With respect to the Normally Open valves of the same series it is 0.5 kg/cm2 with standard diaphragms and 2 kg/cm2 with reinforced diaphragms.
1330/2030 Series Normally Closed diaphragms valves are optionally provided with adjustable slow openings up to 10 sec.
1388 Series valves include a system that allows them to open in two stages, the first of which is quick and with adjustable opening percentage, and the second is time adjustable up to > 20 seconds.
Both 1330 / 2030 and 1332 and 1388 Series are optionally provided with microcontacts for proof of closed valve. 1330 ( 1 ) and 2030 Series have a reed switch, and the others have an SPDT microswitch.
