The S1018 series from Turkish manufacturer SMS-TORK is a 3/2-way general-purpose solenoid valve with a brass body and stainless steel internal components. Configured as normally closed, it uses Viton seals as standard (EPDM and NBR available on request) and handles air, water, gas, and fuel across a temperature span of -10 °C to 160 °C. The DIN 43650 electrical connector and Class H coil insulation (180 °C) support continuous-duty operation at ED 100%.

How does orifice size affect pressure capability?

Three orifice diameters determine the pressure envelope. The 1.8 mm orifice supports 0–4 bar (NC) and 7–16 bar (NO), delivering KV 1.5 L/min. The 2.5 mm drops to 0–3 bar (NC) and 4–12 bar (NO) at KV 3.0 L/min. The 3.5 mm orifice handles 0–1 bar (NC) and 2–10 bar (NO) at KV 5.0 L/min. Larger orifices trade pressure ceiling for higher flow — match the orifice to the system's pressure budget and required KV.

What environmental protections are available?

Standard models carry IP65 ingress protection (ISO 60529), making them suitable for washdown and outdoor installations. IP68-rated enclosures are available on request for submerged or high-humidity duty. Explosion-proof (Ex-proof) coil variants extend the series into ATEX/IECEx hazardous zones. The Class H coil insulation withstands ambient temperatures to 180 °C, ensuring coil integrity in high-temperature environments like steam trace lines and heat transfer fluid control.
