SY223 Series Brass 2/2-Way Solenoid Valve
- Direct Acting, Normally Closed
- Port Size: 1/4"–2"
- Fluid Temperature: -5°C to 80°C (-5℃ to 120℃)
- Operating Pressure: 0.07–1.6MPa
- Media: air, water, oil, gas
SY223 series is a pilot-operated, normally closed 2/2-way brass solenoid valve designed for small industrial spaces, with a 40% volume reduction compared to traditional valves of the same caliber. The valve’s innovative internal mechanism supports 360° omnidirectional installation, unlike traditional solenoid valves, which require directional installation. This design greatly improves the solenoid valve adaptability in complex pipelines and limited spaces.
- 10 mm wide passageway ensures high flow capacity, smooth operation, and high flow
- Optional high-temperature sealing materials (e.g., NBR, EPDM, Viton) extend the valve’s service life
- No water hammer effect (hydraulic shock) or vibration interference, ensuring stable and reliable operations
- The coil is fully encased in thermosetting plastic, providing excellent insulation and protection
- Made of durable material and suitable with multiple media, with low maintenance requirements
- Handheld device and portable machinery
- Compact industrial machinery and automation systems
- Compressed air control systems
- Water treatment systems
- Fluid control equipment
