2/2-way Solenoid Valve with servo diaphragm, G 3/8 - G 2

Transcription

1 2/2-way Solenoid Valve with servo diaphragm, G 3/8 - G 2 Type 6281 can be combined with... User friendly - one solenoid for all orifices Waterhammer free and low noise NC or NO Manual override optional Short installation length Explosion proof types Type 2508 Cable plug Type 1078 Timer Unit Type 2511 ASI Cable Plug Servo-assisted solenoid valve with servodiaphragm for the control of liquid or gaseous Medium. A pressure difference of 0.5 bar is required for a complete switchover. The modular coil system allows the interchange of the coils over all orifices to be in line with the nominal power and circuit.
