About Gate Valves
Gate valves, also known as “sluice valves”, are very common valves seen in many piping systems. Gate valves are used to open up or close off the flow of water, oil, or other liquid.

Typically constructed of metal like iron or steel, gate valves have a large exposed surface through which heat can radiate. Many facilities have rather large numbers of gate valves in use, resulting in massive energy loss in many instances.

Insulating Gate Valves
Gate valves may often require maintenance to prevent or troubleshoot such issues as jamming in open or closed position, rust and corrosion, and leaking. Typical maintenance tasks may include lubrication, cleaning, and replacing seats and other inner components. Due to the need for maintenance and the irregular shape of gate valves, traditional stay-in-place insulation is not practical, therefore requiring a removable product.

Thermaxx Gate Valve Insulation Jackets
Our removable insulation jackets for gate valves are the answer. Use this valve jacket energy savings table and our energy savings calculator to estimate how much you can save by insulating your facility’s gate valves. Thermaxx gate valve jackets have the following features:

  • The Right Fit: We can make jackets for just the bonnet or jackets to cover both the gate valve bonnet and body. Typically, customers prefer a our standard set of gate valve jackets, which includes one for the bonnet and one for the body; this enables easiest access to bonnet. The standard line of gate valve insulation jackets fit class 150 and class 300 valves, in sizes ranging from .5 NPT to 24 inches, with 3 choices of thickness (1/2”, 1”, and 2”) for temperature needs up to 600°F.  We carry jackets for common valve makes including Crane, Nibco, Velan, Hammond, Sarco, and Stockham. We may be also able to custom design insulation jackets to fit your specific needs.
  • Convenient: Our gate valve insulation jackets have Velcro straps and d-ring closures. Seal flaps are used to connect the removable jacket to the adjacent insulation.  The jackets are very easy to remove and replace, and even inexperienced personnel can typically remove or replace the valve jackets in less than five minutes.
  • Cost effective:The standard thickness of our insulation jackets is 1” – 2”, however we can make custom sizes as well.  Our gate valve jackets typically produce a positive return on investment in less than a year, a very attractive payback period.
  • High Quality: Thermaxx insulation jackets set the standard for quality, and we back our valve jackets with an industry-leading 5 year warranty to prove we mean what we say.
