A270

Product catalog summary

Description: The document describes a solenoid valve that is a 2-way normally open, direct-acting poppet type made from stainless steel AISI 316. 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 ranges from -40°C to +60°C depending on the temperature class.

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

Explosion Proof Coil Construction: The housing is available in red color alloy (coil A6) or stainless steel AISI 316 (coil X6), with electrical connections of 1/2” NPT or M20x1.5 on request.

Features: The valve has a maximum allowable pressure of 100 bar and can handle fluid viscosities up to 25 cSt. It is designed for vertical mounting with the coil above and is part of the A270 series. The solenoid valve is not suitable for potentially explosive media.

Technical Specifications: The document provides detailed specifications for various models, including connection sizes, orifice diameters, Kv values, differential pressure ranges, nominal power, and temperature ranges. Example configurations are provided for different connection types and seal materials.

Voltage and Protection: The voltage tolerance for AC is +15% to -10%, and for DC is ±10%. The protection class is IP66, and the valve is rated for continuous service ED100%.

Coils: The document lists coil options for both alternating current (AC) and direct current (DC) across various voltages, with specific series for alloy and stainless steel housings.
