| 250 Series Solenoid Valve | |
The Lee 250 Series Solenoid Valve sets a new standard in reducing space, weight and power consumption. This 2 position, 3-way miniature piloting solenoid valve features Lee's unique and patented MultiSeal technology. The MultiSeal radically simplifies port layout by allowing total porting flexibility 360° around the seal, without the need for O-rings or Anti-Extrusion Rings.
Available in normally open and normally closed models, the 250 Series valve weighs only 0.1 pounds and power consumption is just 4.8 watts at 12 vdc. Special valve models are also available depending on specific customer requirements.
- 2 Position, 3-way, 3000 psi
- Up to 0.31 GPM of flow at 3000 psid (3500 Lohms)
- 12 vdc, 4.8 watts maximum
- 0° to 265 °F temperature range
- Integral safety screen, 0.004 inch hole size
- 0.1 lbs. maximum weight
