AventicsR4120146663/2 Solenoid Shut-Off / Dump Valve, 24 V DC, G1/4 BSPP, 2000 l/min, Series AS1-SOV

Product Description

What this part is:

An AVENTICS Series AS1-SOV solenoid-operated 3/2 directional valve, the electrically actuated soft-start and dump valve module that sits at the head of a modular G1/4 air preparation unit. Energised, it passes supply air to the downstream chain; de-energised it closes the supply and exhausts trapped downstream pressure to atmosphere. It is a poppet valve with an internal pilot, so it takes no external pilot line, and it is block-assemblable within the AS1 modular chain. The SOV designation and the 3/2 in the order code make it a directional shut-off and dump valve rather than a flow control valve: it switches air fully on or fully off and does not meter flow.

Decoding the order code:

AS1: AVENTICS Series AS1 modular air preparation. SOV: shut-off valve, electrically operated (3/2 directional). G014: G 1/4 parallel (BSPP) compressed-air connection rather than NPT. 3/2: three ports, two positions, being supply, outlet and exhaust. 024: 24 V DC coil. FORM C: ISO 15217 form C electrical interface, the small 8 mm industrial valve plug pattern.

What these specs mean in practice:

The coil is 24 V DC and cannot be rewired for mains. The electrical interface is ISO 15217 form C, which takes a form C (8 mm) valve plug. A cordset or plug is not included. The AS1 solenoid is also produced in an M12x1 version, which this build is not.

Minimum working pressure is 2 bar. Below that the internal pilot has nothing to work with and the valve does not shift reliably, so an internally piloted poppet does not suit a low-pressure or vacuum circuit.

Nominal flow of 2000 l/min at G1/4 is generous for the port size and is what makes the SOV suitable as a machine dump valve, where a whole manifold is exhausted quickly rather than one cylinder fed.

Published specifications:

Function: 3/2 directional / shut-off (dump) valve, poppet type. Actuation: electrical, internal pilot. Coil voltage: 24 V DC. Electrical connection: ISO 15217, form C. Nominal flow Qn: 2000 l/min. Working pressure: 2 bar minimum to 10 bar maximum. Compressed air connection: G 1/4 (BSPP). Sealing principle: soft seal. Ambient temperature: −10 °C to +50 °C. Media: compressed air and neutral gases, maximum particle size 25 µm, oil content 0–5 mg/m³. Mounting: modular AS1 chain, block-assemblable. Series: AVENTICS AS1-SOV.

Quantity and configuration:

One valve module. Removed unused from an R480342567 air preparation unit, a new take-out rather than a boxed retail item. Form C valve plug and any connection plates or clamps are not part of this listing.

Mounting data:

AS1 modules are built in both flow hands, left and right air supply. Supply air filtration to 25 µm suits the soft-seal poppet. Published oil carry-over for the series is 0–5 mg/m³.

Interchange guidance:

R412010680 and R412010681 are the same 2000 l/min AS1-SOV function in left- and right-supply builds, related versions with their own hand and voltage. R412014744 is another AS1-SOV variant. The manually operated AS1-BAV shut-off valve occupies the same envelope without a coil.
