Two Types of Valves. There are two common types of earthquake valves available for your home: Seismic Natural Gas Shut-Off Valve. This type of valve triggers when an earthquake occurs with a magnitude of 5.1 and higher. Excess-Flow Valve. This type of valve triggers when there is a gas leak or overpressure surge in your gas line.

We at SIO produce check valves made from materials with the highest quality. Commonly known as one-way valves, check valves are made primarily to block backflow and to protect compressors and pumps. They are common in various industries and applications including natural gas, mining, and municipal water.

The St äubli GMV check valves are designed to allow natural gas to flow in one direction only. With an emphasis on safety, they provide redundant leak protection in the fueling line, prevent

Valves perform various functions throughout the gas delivery system. They block flow by not allowing gas to pass beyond a certain point. Valves isolate pressure by separating two sections of the system that operate at different pressures. They direct flow by determining what path is open for gas to flow. Valves also manage pressure by partially

A cryogenic dual plate check valve and its metallic components are critical to the liquid natural gas supply chain. The sole purpose of these valves is to 

Sandwich these valves between two ANSI flanges for backflow prevention at a fraction of the weight of flanged check valves and a reduced pipeline footprint. Compact Flange-Mount Check

Check Valve. Check valve, also called one-way valve, main function is to prevent backflow and safeguard compressors and pumps. A natural gas check valve ensures smooth flow and gets automatically shut when pressure reduces. Prevents gas and oil from flowing back to the system (backflow). Works even when the oil and gas factory loses power.

In systems requiring burners, such as heater treaters or gas dehydrators, gas is diverted through a natural gas valve like the electrically powered E-LO Control Valve. The valve receives a signal from a temperature sensor. It then opens or closes to provide a corresponding flow of that gas into the vessel's fire tube.

Dual plate wafer check valves are completely different from control and shut-off valves. Some valves work to stop the flow of gas and liquids completely. However, a dual plate check valve allows for the flow of liquid in a single direction. Their intended use case is to protect piping systems, compressors, pumps, and other vital system
