The ETV relief valve is a crucial safety device designed to prevent overpressurization in natural gas systems. When the gas pressure within the system surpasses the predetermined safety limits, the relief valve is triggered, allowing the controlled release of excess gas to prevent hazardous conditions. Once the system pressure returns to a safe level, the valve automatically shuts off, ensuring the system’s continued stability and safe operation.


Advantages of the ETV D1 Relief Valve

Minimizes the risk of explosions and fire by regulating sudden pressure fluctuations in gas systems.

Enhances energy efficiency and extends the operational lifespan of the system.

Features a fully automatic operation, providing ease of use and reliability.

Serves as an optimal safety solution for residential, industrial, and commercial gas applications.


The ETV relief valve is a vital safety mechanism that mitigates the risks of explosions, gas leaks, and equipment damage by preventing overpressurization in gas systems. In the event of a pressure imbalance, it facilitates the safe discharge of excess gas in a controlled manner and subsequently resets automatically. This dual functionality ensures both life safety and the long-term efficiency of the system. Its extensive applicability across residential, commercial, and industrial settings makes it an indispensable component in all gas-powered systems.
