Product catalog summary

Description: The document describes a 3-way solenoid valve, direct acting poppet type, with a construction primarily using AISI 303 and AISI 430FR materials. The valve features a maximum allowable pressure of 50 bar and can handle fluid viscosities up to 25 cSt. It operates in ambient temperatures ranging from -10°C to +80°C and can be mounted in any position.

Construction: The body and armature tube are made of AISI 303, while the plunger and core are AISI 430FR. Springs are constructed from AISI 302, and seal materials include NBR, FPM, and EPDM.

Features: The valve supports options such as a silver shading ring, electroless nickel plating, and explosion-proof coils according to ATEX standards. It also offers an exhaust port with hosetail connection and certified coils. Versions for fluid temperatures as low as -40°C are available upon request.

Specifications: The valve is available in normally closed (NC), normally open (NO), and universal (U) configurations. It supports various connection sizes and orifice diameters, with differential pressure ranging from 0 to 15 bar. Nominal power varies with coil type and temperature range.

Coils: Coils are available for both AC and DC voltages, with a voltage tolerance of +15% to -10% for AC and ±10% for DC. The protection class is IP65 with a connector and IP00 without. Continuous service is rated at ED100%, with options for Class H insulation and special coil voltages.

Spare Parts: The document lists spare parts including the coil fixing nut, coil, plunger, and armature tube assembly.

Overall Dimensions: The document notes that technical and dimensional specifications are subject to modification.
