Product Description

Scope of application

ZCR series is a new type of gas cut-off valve, the main applications are as follows:
1. It is connected with combustible gas leakage monitoring instrument. When the instrument detects the flammable gas leak, it automatically and quickly closes the main gas valve, cuts off the gas supply, and stops the occurrence of malignant accidents in time.
2. Connect with the limit temperature (or pressure) safety controller of the thermal equipment. When the temperature or pressure detected in the equipment exceeds the set limit value, the gas supply valve will be automatically and quickly closed to stop the fuel supply.
3. Connect with the central fire alarm system of the high-rise building. When there is a crisis in the building, the gas supply in the building is automatically cut off to prevent the occurrence of gas explosion.
4, in the city or factory gas supply network set up ZCR gas emergency cut off valve, centralized control in the central control room, remote control, emergency close the accident site of the pipeline supply.
