Product catalog summary

Description: The document describes a solenoid valve, specifically a 3-way direct acting poppet type with flange fixing. It is constructed with a brass body and armature tube, AISI 430FR plunger and core, AISI 302 springs, and seal materials including NBR, FPM, and EPDM.

Features: The valve can withstand a maximum allowable pressure of 50 bar and a maximum fluid viscosity of 25 cSt. It operates in ambient temperatures ranging from -10°C to +80°C, depending on the coil. It supports universal mounting positions. Options include a silver shading ring, electroless nickel plating, and explosion-proof coils according to ATEX standards. An exhaust port with hosetail connection and certified coils are also available. Versions for fluid temperatures as low as -40°C can be requested.

Specifications: The valve series is 312, with various configurations for normally closed (NC), normally open (NO), and universal (U) types. The flange orifice sizes range from 1.2 mm to 1.5 mm, with differential pressure capabilities from 0 to 15 bar. Nominal power varies with coil type, and the temperature range for seals is from -10°C to +140°C.

Coils: Coils are available for both alternating current (AC) and direct current (DC) with various voltage options. They feature Class F insulation, voltage tolerance of +15% to -10% for AC and ±10% for DC, and protection class IP65 with a connector. Continuous service is rated at ED100%. Options include Class H insulation, cable attachment, special coil voltages, and powers.

Spare Parts List: Includes coil fixing nut, coil, plunger, and armature tube assembly.

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