automatic shut-off electric valve with flange connection

     We are producing:

(1): Gas monitoring system (monitors with capacity from 8~1024 channels)

(2): Gas detection system(combustible gas, VOC, toxic gas detectors available)

(3): Gas valves( dimention range from DN15~DN200 with flange or threaded connection)

(4): Other relevant fire-fighting equipment.

• Overview (for Model No.ZH2000-DN25~DN200):

Our industrial-use gas vales are installed in the urban gas pipeline. It can automatically shut-off gas by electric drive mode when meeting emergency. They are all Explosion –proof. When voltage supplied 15% lower than rated value or vales receive external closing control signal, they will shut-off gas automatically. Our vales can be reset only by manual operation. And it can keep open in normal condition.
