0285 2/2-Way Solenoid Valve
Brand: Burkert Fluid Control SystemsThe direct acting plunger solenoid valve Type 0285 is normally closed by spring force. During switching the core of the seal is tightened against the spring force, and opens the valve. The inlet has a gauze filter fitted.
The valve is delivered as standard with a bracket fitment. Type 0285 is best suited to flammable gases.
Features- Direct acting solenoid valve
- Switches without differential pressure
- Gauze filter on inlet
- Brass body
