Technical Data Sheet 
Type 24
2/2-Way solenoid valve
Valve normally closed (NC).
When energized the solenoid first opens the pilot hole and then lifts directly or supported by a 
pressure difference the piston from the valve seat. The valve is closed by spring power.
Type of control: Force pilot operated, no pressure difference 
required
Design: Piston design
Connection: Flanges acc. to EN 1092-1 Form B1/B2
Other flange connections like ASME or JIS on request
Installation: Actuator only in upright position
