This is how a properly insulated valve can save you money and justify the investment with a short Return On Investment (ROI). You will not need any tools or complicated fabrication instructions to install our Thermaxx Jackets. “JUST WRAP and STRAP”.
When maintenance is required our pads are easily removed and quickly reinstalled to save time and money, using your own staff.

*Based on installation of a 1-inch thick R 3 insulating pad on an ANSI 150-pound-class, flanged valve with an ambient temperature of 65 degrees Fahrenheit and zero wind speed.
Example:
Using the table above, calculate the annual fuel and dollar savings from installing a 1-inch thick insulating pad on an un-insulated 6-inch gate valve in a 150-pounds-per-square-inch-gauge (psig) saturated steam line (406°F). Assume continuous operation with natural gas, at a boiler efficiency of 80% and a fuel price of $16.00 per million Btu ($16.00/MMBtu).
Results:
Annual Fuel SAVINGS= 5,800 Btu/hr x 8,760 hr/yr/ (0.80 x 106 Btu/MMBtu) = 50.8 MMBtu
Annual Dollar SAVINGS= 50.8 MMBtu/yr x $16.00/MMBtu = $812.80 on EACH 6-inch valve/yr
