The valve executes an emergency shut-off in less than 1 second (< 1s) upon receiving a DC 12V instantaneous pulse voltage from the alarm system.
After ensuring the leak fault is completely cleared, the valve must be reopened manually by pulling the red handle upwards until it locks in the open state.
The product holds an IP66 ingress protection rating, features an encapsulation-type explosion-proof design marked Ex mb ⅡC T6 Gb, and is certified under CQEx24.1641X.
Standard body materials include Aluminum Alloy and Copper Alloy, with optional 304 Stainless Steel customization available for specific medium requirements.
No, the valve operates in a normally open holding mode with 0W static power consumption. Electrical power (DC 12V pulse) is only used instantaneously to trip the valve closed during an alarm event.
Verify that the box contains 1 product manual, 1 factory inspection report, 1 product certificate, 1 mounting bracket, and installation accessories. Ensure the valve housing has no scratches and labels are intact.
