ZSQ-102/3R DN80 pneumatic two/ three way stop valve
Working Principle
ZSQ-102 / 3R pneumatic two-position stop valve, there are two parts : pneumatic piston actuator and the stop valve.
When no signal is input, the actuator closes the valve spool due to the spring preload, when 0.35MPa air signal pressure, the piston push the stem, down action, so that the valve spool off the lower seat, the flow of media within the pipeline can be switched or cut off.
