3/2-way solenoid valve
for gases and fluids
Type 2508
Cable plug
Type 0340 can be combined with...
• Service friendly manual override
• Analytical pilot valve for increased safety
• Optimized piston design for low switching pressure
• Energy saving impulse coil
• Explosion proof types
Circuit function C
3/2-way valve, when de-energized outlet port
A exhausted, with 3-way pilot control
Circuit function D
3/2-way valve, when de-energized outlet port
B pressurized, with 3-way pilot control
The pilot-controlled 3/2-way solenoid valve
Type 0340 with smoothly operating servopis-
ton requires a differential pressure of 0.5 bar
for complete opening and closing. A 3/2-way
pilot valve (pivoted armature valve) ensures
safe and reliable operation.
