12V Solenoid Valve – 2-Way, Normally Closed, Direct-Acting Electric Solenoid Valve for Air, Gas, and Liquid Control This 2-way, 2-position normally closed solenoid valve controls on/off flow of air, inert gases, liquids, and vacuum. It features a 1/8" BSP threaded connection. The valve 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. 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: - Housing made of anodized aluminum for 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 design for fast response and high sensitivity - Compact and lightweight construction - Designed for automatic control of liquid and gas flow in electrically driven pneumatic systems Specifications: - Voltage: DC 12V - 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) - Port Size: 1/8" BSP - Type: 2-Way, Normally Closed - Operating Media: Air, Gas, Water, Oil, Non-corrosive Liquids - Operation Type: Direct Acting - Flow Direction: Uni-directional - Flow Rate: 0.23 CV (liquid), 22 SCFM at 100 PSI (air) - Working Pressure: 0–1.0 MPa - Maximum Pressure Resistance: 1.2 MPa - Response Time: < 50 ms - Operating Pressure Range: 0–0.8 MPa (operable at vacuum) - Temperature Range: –10°C to +80°C - Power Consumption: 6.5 W - Coil Insulation Class: F - Ingress Protection: IP65 Package Includes: 1 x DC 12V, 1/8" BSP, 2-Way Normally Closed Aluminum Solenoid Valve
