Energy Savings Example

An insulated 6 inch 150# Gate Valve operating at a temperature of 400 degrees Fahrenheit would save a company $864.30 per 6 inch Gate Valve.

 Annual Fuel Savings = 11,372.328 BTU/HR x 8,000 HR/YR = 90.979 MMBTU

Annual Dollar Savings = 90.979 MMBTU x $9.50 MMBTU = $864.30 per 6 inch Gate Valve
