Description
The ASCO S262SH02N3FJ5 is a 1-inch, 2-way normally open gas vent valve used in industrial and commercial fuel gas systems where venting of fuel gas is required in a double block and vent configuration. It is designed for use in vent piping located between shut-off valves to safely allow venting of gas to atmosphere and prevent unintended gas buildup. This valve uses a pilot-operated, zero differential diaphragm design for reliable control and fast response, and it is suitable for natural gas service with ambient temperatures from about -20°F up to 170°F. Typical maximum differential pressure rating is up to about 25 psi, and it has a flow capacity (Cv) of around 19.8. The threaded 1 inch NPT connection simplifies installation and the aluminum body provides corrosion resistance.
Key Features
- Valve is normally open (NO), meaning gas flows through the valve when it is not energized.
- Pilot-operated zero differential diaphragm for controlled vent action.
- Operates on 120 V AC at 60 Hz.
- 1 inch NPT threaded inlet and outlet.
- Flow capacity (Cv) around 19.8 for effective venting performance.
- Die-cast aluminum body for durability.
- 1/8 inch NPT pipe taps with plugs for routine testing.
- Suitable for venting applications in industrial and commercial systems.
