It operates at 24 volts and is calibrated for a water column pressure of 4 inches, indicating its ability to function effectively under substantial pressure. The valve features a 1/2 inch National Pipe Thread (NPT) fitting, making it compatible with standard-sized gas lines. The product is constructed with robust materials to ensure durability and longevity, even in demanding conditions. It's designed for use with natural gas, but can be converted for use with propane if necessary.
