The 2-way, 2-position normally closed air and gas directional control solenoid valve is designed to control the on/off flow of air, inert gases, liquids, and vacuum. This solenoid features a 1/8" BSP thread connection. It remains closed when the coil is de-energized and opens when energized. It has two mounting holes on the bottom and can be installed in any orientation. It is suitable for use in water heaters, drinking fountains, water purification systems, steam generators, HVAC systems, water treatment equipment, cooling systems, and general water industry applications. Features: - Robust anodized aluminum alloy body with corrosion resistance and durability - Heat-resistant Class B insulation on the coil - NBR (Buna-N) sealing material for reliable leak prevention - Direct-acting, normally closed 2-way solenoid valve with fast response and high sensitivity - DC 12V, 1/8" BSP port, compact and lightweight design - Maintains stable flow and prevents dry firing - Normally closed operation: opens with electrical current, closes without current - Designed for automatic control of liquid and gas flow; ideal for electrically driven pneumatic systems Specifications: - Color: As shown - Body Material: Anodized Aluminum - Seal Material: NBR (Buna-N) - Armature Tube Material: Brass - Plunger and Spring Material: Stainless Steel - Dimensions: Approx. 5.5 x 3 x 2.2 cm / 2.16 x 1.18 x 0.86 in (L x W x H) - Type: 2-Way, 2-Position, Normally Closed (NC) - Connection Size: 1/8" BSP - Operating Voltage: DC 12V - Compatible Media: Air, inert gases, water, oil, and other compatible liquids - Operation Type: Direct-acting - Flow Direction: Uni-directional - Flow Rate: 0.23 CV (liquid), 22 SCFM at 100 PSI (air) - Working Pressure: Up to 1.0 MPa (for water, air, gas) - Maximum Pressure Resistance: 1.2 MPa - Response Time: < 50 ms - Operating Pressure Range: 0–0.8 MPa (including vacuum operation at 0 PSI) - Operating Temperature Range: –10°C to +80°C - Coil Power: 6.5 W - Coil Insulation Class: Class F - Ingress Protection: IP65 Package Includes: 1 x DC 12V, 1/8" BSP, 2-Way Normally Closed Aluminum Solenoid Valve with Lead Wires
