Product catalog summary

Description: The document describes a solenoid valve that is a 2-way, normally open, direct-acting poppet type. It features an explosion-proof coil certified for hazardous areas with ATEX II 2GD Ex d IIC T6, T5, or T4 Gb, and Ex tb IIIC T80°C, T95°C, or T130°C Db IP66 ratings. The ambient temperature range varies depending on the temperature class (T6: -40°C to +35°C, T5: +50°C, T4: +60°C). Additional certifications such as EAC, INMETRO, and CCOE are available upon request.

Valve Construction: The valve body and seal assembly are made of brass, with core and plunger constructed from AISI 430FR, springs from AISI 302, and the armature tube from AISI 316. Seal materials include NBR, FPM, and EPDM.

Explosion Proof Coil Construction: The housing is made of a red-colored alloy painted with epoxy powder, with electrical connections available in 1/2” NPT or M20x1.5 upon request.

Features: The valve supports a maximum allowable pressure of 100 bar and a maximum fluid viscosity of 25 cSt. It is designed for mounting with the coil in a vertical position. Options include stainless steel coil housing, electroless nickel plating, stainless steel seat insert (up to Ø4.5), and manual override.

Series A206: Connection options include A=1/8”, B=1/4”, C=3/8”, and D=1/2”. The document provides examples of configurations, such as A206BV25///A61, which specifies connections, seal type, orifice size, voltage, and housing material.

Coils: The document lists coil options for both alternating current (AC) and direct current (DC) with voltage tolerances of AC +15% -10% and DC ± 10%. The protection class is IP66, and the coils are rated for continuous service (ED100%).

Technical Specifications: The document includes tables detailing connection sizes, orifice diameters, Kv values, differential pressure ranges, nominal power, and temperature ranges for various configurations.
