EMV Series Mechanical Earthquake Valve
The EMV series mechanical earthquake valve is a critical safety device designed to automatically shut off gas flow upon detecting seismic activity, such as earthquakes. This device complies with the TS 12884 standard and is manually installed, significantly reducing the risk of fire hazards by activating the gas shut-off mechanism when it detects vibrations.
EMV series mechanical earthquake valve is a normally open, manually operated safety valve that has a sensing device and drive mechanism that detects oscillations or systematic movements (earthquake) and automatically closes the gas supply to the gas installations in residential and similar places by mechanical means upon the effect-signal of these devices and remains closed until it is installed with a special tool.
Key Advantages of Gas and Earthquake Valves
Equipment Protection: The earthquake valve automatically stops gas flow within the pipeline during an earthquake, preventing gas leaks and potential fires, thereby ensuring the safety of connected equipment.
Operational Efficiency: By preventing gas leaks, the valve maintains stable system operation, enhancing overall efficiency.
Energy Conservation: By cutting off gas flow, it mitigates unnecessary gas consumption, reducing energy waste and operational expenses.
Environmental Compliance: By preventing gas leaks, earthquake valves minimize environmental hazards and contribute to reducing pollution.
Thermal and Mechanical Durability: Designed for high thermal and mechanical resilience, earthquake valves maintain safe and long-term functionality, even in demanding operating conditions.
Installation and Compliance Considerations
The valve must be securely fixed to the building’s structure, ensuring accurate detection of seismic activity and proper gas supply shutdown during an earthquake.
Installing the valve alone is not sufficient for comprehensive fire safety in gas installations; additional safety measures should be considered.
The product must be used in full compliance with applicable legal regulations and the manufacturer's instructions.
Operational Mechanism of Mechanical Earthquake Valves
Mechanical earthquake valves are engineered to detect seismic movements using precisely calibrated mechanisms. Upon reaching specified acceleration and frequency thresholds, as defined under the TS 12884 standard, the valve automatically shuts off gas flow. This function prevents gas leaks and minimizes fire risks that may arise during an earthquake, ensuring enhanced safety and regulatory compliance.
