Valve jacket insulation is a great way to insulate three-way valves. Since they are provided with velcro straps and pull cords, these jackets perfectly fit around three-way valves leaving no room for heat loss. The valves also remain protected from dirt, impurities and dust when they are insulated valve covers. 

In our expert option, valve jackets are the best way to insulate three-way valves because:

  • Manufacture: Valve covers that we supply here at Buy Insulation Online are made with superior quality silicone coated glass cloth. The cloth is sewn around 25 - 50mm Rockwool or sager. Valve jackets made for both external and internal applications are made the same way giving you a superior, professional finish, no matter where it is used. 
  • Thermal Insulation: The high-quality mineral wool insulation used ensures that three-way valves do not lose heat. It helps save energy and money and makes your building energy-efficient. The pull cords and velcro strap enable easy installation. Not only that, but they also ensure that valve covers fit perfectly around three-way valves, leaving no gaps, hence no way for heat loss.  
  • Easy to Maintain: As mentioned earlier, valve covers can be easily installed around three-way valves. They can just as easily be removed for maintenance purposes. They are easy to use, unlike traditional, hard insulation. 
  • Safer Workplace: Valve jackets help protect personnel from contact with the hot surface of the three-way valve. They also improve workplace safety by preventing heat loss in valves and keeping issues like condensation or seating away. Since valve covers reduce the likelihood of condensation in valves they minimise the formation of small water pools in the workplace, which could lead to accidental slips or mishaps.
