In case of detection of a combustible gas leak, they are used in conjunction with gas alarms that provide, in case of gas contamination, the issuance of an electric impulse to operate the valve. The valve has a normally open design. The threads are internal 3/4 inch (DN25A). The control pulse is 12V. This valve is in the standby state in the open state, without consuming any energy. When a power pulse is applied to it, the valve immediately switches to the closed state. It remains in this state until the button is returned to its original state.
