Product catalog summary

Specifications:
The document details the specifications of a solenoid valve, specifically a 2-way normally closed valve made from stainless steel AISI 316. It is direct acting and poppet type, suitable for non-explosive media. The valve is equipped with an explosion-proof coil certified for hazardous areas under ATEX standards.

Valve Construction:
The valve body, armature tube, and springs are made from AISI 316, while the plunger and core are AISI 430FR. The shading ring is silver, and seals are available in NBR, FPM, or EPDM.

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

Performance Parameters:
The maximum allowable pressure is 100 bar, with a fluid viscosity limit of 25 cSt. The ambient temperature range varies with the coil type: -40°C to +35°C for T6, up to +50°C for T5, and up to +60°C for T4.

Electrical Specifications:
Voltage tolerance for AC is +15% to -10%, and for DC is ±10%. The protection class is IP66, and the service is continuous (ED100%).

Connection and Orifice Details:
The document provides a table with connection sizes (1/4”, 3/8”, 1/2”), orifice sizes, Kv values, and differential pressure limits for both AC and DC. The series and seal types are also specified.

Example Configurations:
Examples include configurations with different housing materials and seal types, such as A170BV12///A6B for alloy housing and A170BV12///X6B for stainless steel housing.

Additional Features:
The valve is designed for vertical mounting with the coil above and has a weight of 0.66 kg. Modifications to technical and dimensional specifications are reserved.
