Solenoid Diaphragm Valve 2/2-Way - Series 242/242FL | AWS

Electromagnetic Diaphragm Valve 2/2 AWS Type 242 / 242FL

The AWS Type 242 is a 2/2-way seat valve with a diaphragm, featuring forced pilot operation. Due to its positive lift, it operates from 0 bar differential pressure, unlike standard pilot-controlled diaphragm valves. The basic configuration is NC (Normally Closed).

Technical Data

• 242 Threaded: DN 16–50, G 3/8” to G 2”
• 242FL Flanged: DN 15–100, flanges according to DIN EN 1092-1
• Pressure: 0–10 bar, with reduced values in DC and DN 65–100
• Body Materials: Brass or 1.4308 for 242, 1.4308 for 242FL
• Seals: NBR, EPDM, FKM
• Medium Temperature: -10 to +130 °C, depending on elastomer
• Viscosity: ≤20 cSt
• Coil Protection: IP65 with mounted plug

Flow and Size Selection

The threaded version covers Kv 4.1 to 41.2 m³/h. The 242FL covers Kv 4.1 to 136.5 m³/h, with DN 65–100 at 0–6 bar pressure. DN selection is based on required flow, available pressure, permissible pressure drop, and line connection type.

Electrical Configuration

Connection is according to DIN EN 175301-803 Form A. Available in 230 V AC 50/60 Hz, 24 V DC, and special voltages, with ±10% tolerance per VDE 0580 and 100% ED duty cycle.

Applications

Suitable for clean water, neutral liquids, compressed air, and compatible gases without solids. Used in filling/draining lines, process water networks, HVAC, auxiliary circuits, and skids where operation without minimum Δp is required.

Options

NPT, flange DN 25–100, NO version, manual override, bracket, LED plug, oil-free/grease-free cleaning, silicone-free/LABS-free, Ex coil up to DN 25 for NC 0–6 bar, and optional WRAS diaphragm in 242FL.
