Gas and earthquake valves are important components that protect industrial machines by capturing dust and particles carried during gas flow and increase safety by detecting seismic movements and automatically shutting off. EGV ensures that fine particles (such as dust and rust) in the gas are captured, while EMV series mechanical earthquake valves automatically cut off the gas flow by detecting seismic movements.
EGV series automatic gas shut-off valve is a safety valve installed on gas lines outside the residence.
When assembled on the production lines, the device is activated by manually pulling the reset lever upward, which opens the orifice surface inside the device for gas flow. As a result, the valve assumes its normally open position, allowing gas from the line to pass to the user side. During normal operation, the product functions in this open position without any electrical consumption, allowing gas to flow through. The automatic gas shut-off valve, designed for safety purposes, activates when it receives an electrical signal from a compatible connected device. Upon receiving this signal, the internal mechanical drive system is triggered. This action causes the shaft connected to the reset lever to move toward the orifice surface, sealing the gas passage area using a suitable gasket mounted on the shaft. This seals the orifice in a leak-proof manner, cutting off the gas flow in the line and keeping the valve in a closed state.
Advantages of Automatic Gas Shut-Off Valves
Device Protection: Automatic gas shut-off valve can receive the electrical signal in question from a gas alarm device or a similar signal generating device to which it is electrically connected.
Efficient Operation: It allows machines to operate stably and efficiently by preventing contaminated gas flow, thus increasing system performance.
Energy Saving: Clean and regular gas flow prevents excessive energy consumption of machines and provides savings by increasing energy efficiency.
Environmentally Friendly: Automatic Gas Shut-Off Valves create an environmentally friendly working environment by reducing industrial air pollution and contribute to the protection of nature.
Thermal and Mechanical Durability: Valves are resistant to thermal and mechanical stresses encountered in operating conditions, thus providing long-term and safe use.
The automatic gas shut-off valve can receive the electrical signal in question from a gas alarm device or a similar signal generating device to which it is electrically connected. The most common use is in conjunction with a gas alarm device. In this use, in the event of any inappropriate gas leakage in the area where the gas alarm device is located, the automatic gas shut-off valve, which receives an electrical signal from the alarm device, automatically cuts off the gas flow in the line to which it is installed and stops the passage in the gas line until it is manually installed again for safety purposes. The EGV series automatic gas shut-off valve is a safety valve installed on gas lines outside the residence and used for safety purposes. When it receives an electrical signal, the mechanical drive system is activated, cuts off the gas flow and keeps the line in the closed position. It is usually used in conjunction with gas alarm devices and provides safety by automatically cutting off the gas when a gas leak is detected.
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.
