Detailed Description

The 3” Gas Fuel Isolation Valve is designed for use in industrial gas turbines within the oil and gas sector, serving as a vital safety and control device. It regulates the flow of natural gas or compressor discharge air to the turbine, enabling quick isolation of fuel supply during abnormal or emergency conditions to protect the turbine from damage.

This valve features a three-inch outlet flange and is solenoid-pilot actuated, operating on 24 or 95-140 VDC power. It is engineered to withstand high-pressure environments, with natural gas operation rated up to 900 psig and compressor air up to 640 psig. It also endures elevated temperatures, tolerating heat soak conditions up to 400°F for natural gas and up to 800°F for compressor air applications.

Constructed from stainless steel materials compliant with NACE standards, the valve resists corrosion in harsh operating conditions typical in oil and gas facilities. It meets strict safety certifications, including CE-ATEX Group IIA, Category 3, Zone 2, T3, making it suitable for use in potentially explosive atmospheres.

The valve operates with a rapid opening time of approximately 110 milliseconds and closes within 1 second, enabling prompt response to operational changes or emergency shutdown signals. Typically installed in pairs to provide dual-redundancy, these valves enhance system safety by ensuring backup isolation capability.

Overall, the 3” Gas Fuel Isolation Valve is essential for maintaining safe, efficient, and reliable turbine operation by controlling and isolating fuel or air flow, thereby preventing damage and reducing the risk of costly downtime in oil and gas power generation applications.
