0344

3/2 way Solenoid Valve for compressed air and vacuum applications • Service friendly manual override • Vacuum specific version • Optimized piston design for low switching pressure • Energy saving impulse coil Type 0344 can be combined with...

Type 2508 Cable plug

The pilot-controlled 3/2 way valve Type 0344 with a smoothly operating servo-piston requires a differential pressure of 0.25 bar for complete opening and closing. A 3/2 way pilot valve (pivoted armature valve) ensures safe and reliable operation.It is available in circuit function C and D. An additional return spring ensures reliable switching behavior at low pressures and vacuum. 2(A)

This dimensional drawing shows a valve in circuit function C with the port specifications P, R and A/B (manual override via port P). In circuit function D the manual override is located above the port A/B (pilot rotated 180° compared to circuit function C). (Vacuum pump connected at port R, atmospheric pressure connected at port P.)
